Is Glucose A Compound Or A Molecule?

Definition Of Compound - Chemistry Dictionary

A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures , the substances present are not chemically bonded together. Water: two hydrogen atoms bonded to an oxygen atom. The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds . The elements in any compound are always present in fixed ratios. Example 1:Pure water is a compound made from two elements - hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom. Example 2: Pure table salt is a compound made from two elements - sodium and chlorine. The ratio of sodium ions to chloride ions in sodium chloride is always 1:1. Example 3:Pure methane is a compound made from two elements - carbon and hydrogen. The ratio of hydrogen to carbon in methane is always 4:1. Example 4:Pure glucose is a compound made from three elements - carbon, hydrogen, and oxygen. The ratio of hydrogen to carbon and oxygen in glucose is always 2:1:1. Compounds can be decomposed chemically into their constituent elements. Further differences between compounds and mixtures are listed in the definition of mixture . Continue reading >>

Carbohydrates

Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP Monosaccharides Monosaccharides are the simplest carbohydrates and are often called single sugars. They are the building blocks from which all bigger carbohydrates are made. Monosaccharides have the general molecular formula (CH2O)n, where n can be 3, 5 or 6. They can be classified according to the number of carbon atoms in a molecule: n = 3 trioses, e.g. glyceraldehyde n = 5 pentoses, e.g. ribose and deoxyribose ('pent' indicates 5) n = 6 hexoses, e.g. fructose, glucose and galactose ('hex' indicates 6) There is more than one molecule with the molecular formula C5H10O5 and more than one with the molecular formula C6H12O6. Molecules that have the same molecular formula but different structural formulae are called structural isomers. Glyceraldehyde's molecular formula is C3H6O3. Its structural formula shows it contains an aldehyde group (-CHO) and two hydroxyl groups (-OH). The presence of an aldehyde group means that glyceraldehyde can also be classified as an aldose. It is a reducing sugar and gives a positive test with Benedict's reagent. CH2OHCH(OH)CHO is oxidised by Benedict's reagent to CH2OHCH(OH)COOH; the aldehyde group is oxidised to Continue reading >>

Is Glucose, Vitamin C, Ammonia, And Water A Molecule Or Compound? | Yahoo Answers

Is glucose, vitamin c, ammonia, and water a molecule or compound? Are you sure you want to delete this answer? Best Answer: They are all molecules and compounds. Compounds are molecules made of atoms of different elements. Molecule is 2 or more atoms bonded together. All of the things you mentioned fit both of these definitions categorically. - A molecule is formed when two or more atoms join together to form something different. - A compound is something that contains more than one element (or type of atom. if you prefer). All compounds, therefore, are molecules. We just need to know which molecules are the compounds. Glucose = 12 Hydrogen / 6 Carbon / 6 Oxygen There's more than one element here, so this is both a molecule (because there is more than one atom) and a compound (because there is more than one type of atom). ______________________________________... Vitamin C = 8 Hydrogen / 6 Carbon / 6 Oxygen Again, this is both a compound and a molecule, because there is more than one type of atom here. ______________________________________... A compound and a molecule, because there are two elements here. ______________________________________... Both a compound and a molecule once more. Upload failed.

Molecular Structure Of Glucose

What I wanted to do in this video is familiarize ourselves with one of the most important molecules in biology And that is Glucose sometimes referred to as Dextrose and the term Dextrose comes from the fact that the form of Glucose typically Typically found in nature if you form a solution of it, it's going to polarize light to the right and Dextre means Right But the more typical term glucose this literally means sweet in greek if you ask a greek friend to say sweet it sounds like Lucas or I'm not saying it perfectly, but it sounds a lot like a glucose And that's because that's where the word comes from and it is super important because it is it is it is how energy [is] stored and transferred in biological systems in fact right [now] when if someone were to talk about your blood your blood sugar they're talking about the glucose content, so when people talk about blood blood sugar they're talking about your they're talking about your glucose content the whole process of photosynthesis this is all about plants using harnessing the [sun's] energy and storing that energy in the form of glucose when we talk about when we talk about things like respiration in our in our cells cellular respiration that's all about taking glucose and using it to full and to create atp's which are the molecular currency of energy Inside of our body, so these are in credit is an incredibly important molecule We can start wreaking chains of glucose to form Glycogen to form Starches this along with another similar another simple sugar fructose you can use to form our table sugar But even glucose by itself is sweet so let's get familiar with it as a molecule so immediately When you look at this is it kind of drawn as a as an open chain we see that we have one two three Actually, let me number thes Continue reading >>

Glucose

This article is about the naturally occurring D-form of glucose. For the L-form, see L-Glucose. Glucose is a simple sugar with the molecular formula C6H12O6, which means that it is a molecule that is made of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Glucose circulates in the blood of animals as blood sugar. It is made during photosynthesis from water and carbon dioxide, using energy from sunlight. It is the most important source of energy for cellular respiration. Glucose is stored as a polymer, in plants as starch and in animals as glycogen. With six carbon atoms, it is classed as a hexose, a subcategory of the monosaccharides. D-Glucose is one of the sixteen aldohexose stereoisomers. The D-isomer, D-glucose, also known as dextrose, occurs widely in nature, but the L-isomer, L-glucose, does not. Glucose can be obtained by hydrolysis of carbohydrates such as milk sugar (lactose), cane sugar (sucrose), maltose, cellulose, glycogen, etc. It is commonly commercially manufactured from cornstarch by hydrolysis via pressurized steaming at controlled pH in a jet followed by further enzymatic depolymerization.[3] In 1747, Andreas Marggraf was the first to isolate glucose.[4] Glucose is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.[5] The name glucose derives through the French from the Greek γλυκός, which means "sweet," in reference to must, the sweet, first press of grapes in the making of wine.[6][7] The suffix "-ose" is a chemical classifier, denoting a carbohydrate. Function in biology[edit] Glucose is the most widely used aldohexose in living organisms. One possible explanation for this is that glucose has a lower tendency than other aldohexoses to react nonspecific Continue reading >>

Bbc - Gcse Bitesize: Compounds In Living Organisms

The biosphere refers to all living organisms, both plants and animals, on Earth. Living things are mainly made from compounds that contain the elements carbon, hydrogen, oxygen and nitrogen. There are smaller amounts of other elements such as phosphorus and sulfur. There are also traces of most of the other elements. Proteins are polymers. They are built up by the joining together of monomers called amino acids. There are only 20 different amino acids, but each protein molecule has hundreds, or even thousands, of them joined together in a unique sequence. This gives each protein its own individual properties. The proteins in hair, skin and muscle each have properties suited to their function. The diagrams show two of these amino acids: Carbohydrates have the empirical formula CH2O. This means that each carbohydrate has twice as many hydrogen atoms as carbon or oxygen atoms. The simplest carbohydrates are sugars such as glucose. These sugar molecules can polymerise to make giant carbohydrate molecules such as starch and cellulose. Glucose has the molecular formula C6H12O6. The structure of a glucose molecule is shown in the diagram below: Fats are also compounds of carbon, hydrogen and oxygen. They are esters of fatty acids and glycerol. Continue reading >>

What Is Glucose? - Formula, Definition & Regulation

The glucose molecule is an important carbohydrate, essential for the production of ATP, or the molecule of energy in the body. Glucose is tightly regulated, and both excessive and inadequate glucose levels result in disease states. What Is Glucose? The name glucose is from the Greek word for 'sweet' , which is 'glukus.' Glucose is a monosaccharide, which is another term for a simple sugar. It is one of three monosaccharides that are used by the body, but it is the only one that can be used directly to produce ATP. ATP is used by the body for energy; in fact, ATP is the only molecule that can be used for energy. Thus, adequate glucose levels are essential. Glucose is both helpful and harmful to organisms. As mentioned, glucose is used by cells to make ATP and power the body. Hyperglycemia (high blood glucose), however, is cytotoxic (cell-killing) and can induce severe inflammation throughout the body. Hypoglycemia (low blood glucose) occurs when there is not enough glucose in the blood. This too is harmful and potentially deadly. The body has several ways to detect changing glucose levels and mechanisms to correct harmful situations. When the body cannot regulate glucose levels, diseases such as diabetes occur. Regulation When you eat, the carbohydrates in your food are either already simple sugars or are re-broken down into simple sugars. The simple sugars are readily absorbed into your bloodstream from your digestive system, causing your blood glucose level to rise. Your pancreas detects rising blood glucose and responds by secreting insulin. Insulin is a regulatory molecule whose purpose is to control carbohydrate and fat metabolism. Once released into the blood, insulin directs cells of the liver, skeletal muscle, and fat tissue to absorb glucose from the blood. Once Continue reading >>

Compounds: Facts (science Trek: Idaho Public Television)

Atoms and Elements: The Building Blocks of Everything Everything that takes up space in our world is matter . The science of studying matter is called chemistry . All matter is made of tiny particles called atoms . Atoms make up the air, the water, your body, your clothes, the food you eat and the chair you are sitting on. But you can't see atoms. They are so tiny that there are billions of atoms just in the period at the end of this sentence. There are different types of atoms, and they fit together in special ways to make up all of the matter in the world. All atoms are made up of even tinier particles called protons , neutrons , and electrons . The protons and neutrons huddle together in the nucleus , or center, of the atom, while the electrons spin around the nucleus. Everything in the universe is made from elements . We know of 92 elements that occur in nature, but several more have been created by scientists for a total of 118. An element is a pure substance that is made from one single type of atom. For example, gold is an element that is made up of gold atoms. Oxygen is an element made up of oxygen atoms. The Periodic Table of Elements is used to organize the elements by their atomic number, or the number of protons in the nucleus. For example, oxygen has 8 protons, so its atomic number is 8. Chemical symbols stand for each element. There is much more you can learn about atoms and elements from the periodic table . When two or more atoms join together, we call it a molecule . When two or more atoms of different elements join together, we call it a compound . All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. Continue reading >>

What Elements Make Up Glucose?

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. Produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. Chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch. Glucose is a hydrocarbon, so it contains -- you guessed it -- carbon and hydrogen. It also contains oxygen. Carbon is the fourth most abundantly occurring element in the universe and is found in all known living things, making it the chemical foundation of known life. Every glucose molecule contains six atoms of carbon. One of those is grouped with one atom each of oxygen and hydrogen to form an aldehyde group, making glucose an aldohexose. Carbon is both a waste product and an energy source in cellular respiration occurring with glucose molecules and forms the base element in the cellular respiratory cycles of glycolysis and the subsequent Kreb's cycle in which glucose is transformed into energy. Glucose can also be transformed into other energy compounds like galactose by oxidizing a singular carbon element within the glucose molecule. The lightest and the most abundantly occurring element in the universe, hydrogen accounts for nearly 3/4 of the entire universe's mass. There are 12 hydrogen atoms found in each glucose molecule. Although it does not bond well with carbon directly in its elemental form, reactions between the non-elemental forms of the two elements do form molecules containing the carbon-hydrogen bond which is found in most, if not all organic compounds--like glucose. Its high reactivity to electronegative elements, including oxygen, results in Continue reading >>

Studying Sugar Compounds, Molecular Activity And Breakdown

The Compound Sugar: Explanation and Molecular Breakdown written by: Dawn Marcotte edited by: Donna Cosmato updated: 2/5/2013 Is sugar a compound? Sugar is not only a compound, it is a basic requirement for all life both plant and animal. The characteristics and uses of different types of sugar are outlined with examples of the three major categories. Students may ask, "Is sugar a compound?" The answer is yes, not only is it a compound, sugar is an extremely important organic compound. It comes in various forms but is used by every living organism as a source of energy. Sugars can be divided into three categories: Single sugars, double sugars and complex sugars. Each has its own molecular breakdown, physical characteristics, and uses by living organisms. All sugars are a combination of carbon, hydrogen and oxygen in such a way that there are two hydrogen atoms for each carbon atom. There is one oxygen atom for each carbon atom as well. This simple structure allows single sugars to combine into double or complex sugars for plant and animals to use. The two most common single sugars are glucose and fructose. Glucose is also called dextrose. These simple sugars are often listed as ingredients on food and beverage labels. Glucose is used by humans for energy and is found in the bloodstream. Individuals with diabetes have a blood sugar level that is too high and their bodies cant process the compound. This inability to metabolize sugar can cause serious physical symptoms. There are man-made alternatives to sugar available for those individuals. Glucose has 6 carbon and oxygen atoms and 12 hydrogen atoms. When the atoms are metabolized in the human body, they produce carbon dioxide, water and nitrogen compounds while they produce energy for the cells in the body to use. Plant Continue reading >>

The Glucosee Molecule - Chemical And Physical Properties

To View the Glucose Molecule in 3D --->>in 3D with Jsmol Glucose a simple monosaccharide sugar, is one of the most important carbohydrates and is used as a source of energy in animals and plants. Glucose is one of the main products of photosynthesis and starts respiration. The natural form (D-glucose) is also referred to as dextrose, especially in the food industry. A Haworth projection representation of the structure of glucose Glucose (C6H12O6) is a hexose -- a monosaccharide containing six carbon atoms. Glucose is an aldehyde (contains a -CHO group). Five of the carbons plus an oxygen atom form a loop called a "pyranose ring", the most stable form for six-carbon aldoses. In this ring, each carbon is linked to hydroxyl and hydrogen side groups with the exception of the fifth atom, which links to a 6th carbon atom outside the ring, forming a CH2OH group. This ring structure exists in equilibrium with a more reactive acyclic form, which makes up 0.0026% at pH 7. Glucose is a ubiquitous fuel in biology. We can speculate on the reasons why glucose, and not another monosaccharide such as fructose, is so widely used. Glucose can form from formaldehyde under abiotic conditions, so it may well have been available to primitive biochemical systems. Probably more important to advanced life is the low tendency of glucose, by comparison to other hexose sugars, to nonspecifically react with the amino groups of proteins. This reaction (glycosylation) reduces or destroys the function of many enzymes. The low rate of glycosylation is due to glucose's preference for the less reactive cyclic isomer. In respiration, through a series of enzyme-catalysed reactions, glucose is oxidized to eventually to form carbon dioxide and water , yielding energy, mostly in the form of ATP .
