Glucose Syrup - Wikipedia
Glucose syrup, also known as confectioner's glucose, is a syrup made from the hydrolysis of starch . Glucose is a sugar . Maize (corn) is commonly used as the source of the starch in the US, in which case the syrup is called " corn syrup ", but glucose syrup is also made from potatoes and wheat , and less often from barley , rice and cassava . [1] p.21 [2] Glucose syrup containing over 90% glucose is used in industrial fermentation , [3] but syrups used in confectionery contain varying amounts of glucose , maltose and higher oligosaccharides , depending on the grade, and can typically contain 10% to 43% glucose. [4] Glucose syrup is used in foods to sweeten, soften texture and add volume. By converting some of the glucose in corn syrup into fructose (using an enzymatic process), a sweeter product, high fructose corn syrup can be produced. Depending on the method used to hydrolyse the starch and on the extent to which the hydrolysis reaction has been allowed to proceed, different grades of glucose syrup are produced, which have different characteristics and uses. The syrups are broadly categorised according to their dextrose equivalent (DE). The further the hydrolysis process proceeds, the more reducing sugars are produced, and the higher the DE. Depending on the process used, glucose syrups with different compositions, and hence different technical properties, can have the same DE. The original glucose syrups were manufactured by acid hydrolysis of corn starch at high temperature and pressure. The typical product had a DE of 42, but quality was variable due to the difficulty of controlling the reaction. Higher DE syrups made by acid hydrolysis tend to have a bitter taste and a dark colour, due to the production of hydroxymethylfurfural and other byproducts. [1] p.26 Th Continue reading >>
What Is A Standard Glucose Solution?
Robin Wasserman has been writing and prosecuting biochemical patents since 1998. She has served as a biochemical patent agent and a research scientist for a gene-therapy company. Wasserman earned her Doctor of Philosophy in biochemistry and molecular biology, graduating from Harvard University in 1995. Vials of glucose solution sit on a shelf, with one that has reacted to a chemical and has turned light green leaning out.Photo Credit: Aydn Mutlu/iStock/Getty Images A standard solution of glucose contains a known quantity of glucose in a known quantity of water. Scientists use standard glucose solutions to measure the concentration of a glucose in an unknown solution. These tests are helpful in many research experiments but also find practical medical application when testing patients for diabetes. Glucose is a 6-carbon sugar molecule, the most common carbohydrate in your body. People often refer to glucose as "blood sugar" as it circulates throughout your blood at a concentration of about 65 to 110 mg/mL. Classified as a monosaccharide, an aldose, a hexose and a reducing sugar, glucose chemically reduces other compounds in oxidation/reduction reactions by readily donating electrons. Glucose is also known as dextrose or D-glucose, due to its dextrorotatory property, the ability of glucose solutions to rotate plane polarized light to the right. Standard solutions in general contain a known amount of substance dissolved in a known quantity of another substance. Usually, a standard glucose solution refers to a 1-percent glucose solution. Preparing a 1-percent standard glucose solution involves dissolving 1 g of glucose in 100 ml of water. Glucose standard solutions are used to create calibration curves against which unknown solutions are measured. These curves then help de Continue reading >>
Ap Lab1 Osmosis Sample4
Atoms and molecules are the building blocks of cells. Both have kinetic energy and are constantly in motion. They continually bump into one another and bounce off into new directions. This action results in two important processes, diffusion and osmosis. Diffusion is the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration. Cells have selectively permeable membranes that only allow the movement of certain solutes. Diffusion is vital for many of lifes functions in a cell. It allows oxygen and carbon dioxide exchange in the lungs and between the bodies of intracellular fluid and cells. Diffusion also aids in the transport of nutrients and water in the xylem and phloem of plants. In those plants, it permits for the absorption of water into roots. An example of this process is the diffusion of a smell in a room. Eventually dynamic equilibrium will be reached. This means that the concentration of the molecules carrying the smell will be approximately equal through out the surrounding enclosed area and no net movement of the molecules will occur from one area to another. Osmosis is special kind of diffusion. It is the diffusion or movement of water through semi-permeable membranes from a region of higher water potential (hypotonic solute) to a region of lower water potential (hypertonic solute). Water potential is the measure of free energy of water in a solution. There are three types of solutions. Isotonic solutions have an equal concentration of solute on both sides of the membrane, and dynamic equilibrium has been reached in the solution. Hypertonic solutions have a higher concentration of solute on one side of the membrane than the other. Hypotonic solutions are the opposite of hypertonic solutions. A sol Continue reading >>
How To Prepare A Glucose Solution
By Claire Gillespie; Updated April 26, 2018 What you refer to as blood sugar is actually glucose, a simple sugar that comes from the carbohydrates you eat and that converts to an important energy source for the body. In powdered form, glucose is combined with other sugars and added to food to make it sweeter, or used as a nutritional supplement for athletes. It's easy to prepare a glucose solution at home to use for a number of experiments. When a known quantity of glucose is mixed with a known quantity of water, it is known as a standard glucose solution. Scientists use standard glucose solutions to measure the concentration of glucose in an unknown solution. Glucose solutions are also used in a number of research experiments and to measure blood glucose levels in people with diabetes or suspected diabetes. These tests measure whether the body can cope with large amounts of sugar. If the blood sugar recorded in the test is higher than a certain point, the cells in the body may not be absorbing enough sugar, which may be caused by diabetes. Work out the Total Volume and Percentage Glucose Solution To work out how much glucose you need to make a solution of a given percent, multiply (mass/volume) by volume, bearing in mind that 1 g in 100 ml is a 1 percent solution. For this example, if you want to make a total solution of 500 ml of 20 percent glucose, multiply (20/100) by 500. The answer is 100, so you need 100 g of powdered glucose. (If you were making a 10 percent glucose solution, the calculation is (10/100) x 500, and the answer is 50 g). Pour 250 ml of Deionized Water Into a 500 ml Beaker Insert a stir bar and sit the beaker on a hot plate. Turn on the heat and stir functions. Let the water heat up, but don't bring it to boiling point, as this will stop the glucos Continue reading >>

Oral Rehydration Therapy (ort) - Rehydration Project
"The discovery that sodium transport and glucose transport are coupled in the small intestine so that glucose accelerates absorption of solute and water (is) potentially the most important medical advance this century." ORT is the giving of fluid by mouth to prevent and/or correct the dehydration that is a result of diarrhoea. As soon as diarrhoea begins, treatment using home remedies to prevent dehydration must be started. If adults or children have not been given extra drinks, or if in spite of this dehydration does occur, they must be treated with a special drink made with oral rehydration salts (ORS). The formula for ORS recommended by WHO and UNICEF contains: The Canadian Journal of Paediatrics 1994; 1(5): 160-164 Oral rehydration therapy with an inexpensive glucose and electrolyte solution as promoted by the World Health Organization has reduced substantially the number of deaths from dehydration due to diarrhea. In addition, recent research suggests that these solutions have advantages over conventional therapy. Yet, oral rehydration therapy has not been used extensively in developed countries. Acute gastroenteritis is one of the most common illnesses affecting infants and children in Canada and the world. The average child under age 5 experiences 2.2 diarrheal episodes per year.1 Treatment from resulting dehydration accounts for an estimated 200,000 hospitalizations per year in the U.S.2 with comparable rates occurring in Canada. Worldwide as many as 4,000,000 children per year die as a result of gastroenteritis and resulting malnutrition. Prolonged diarrhea and malnutrition are a primary cause of morbidity and mortality in Canadian native populations. Oral rehydration therapy (ORT), using a simple, inexpensive, glucose and electrolyte solution promoted by the Continue reading >>
Ch150: Chapter 7 - Solutions - Chemistry
Video showing the crystallization of a supersaturated solution of sodium acetate. Video by : North Carolina School of Science and Mathematics So how can we predict the solubility of a substance? One useful classification of materials is polarity. As you read about covalent and ionic compounds in Chapters 3 and 4, you learned that ionic compounds have the highest polarity forming full cations and anions within each molecule as electrons are donated from one atom to another. You also learned that covalent bonds could be polar or nonpolar in nature depending on whether or not the atoms involved in the bond share the electrons unequally or equally, respectively. Recall that the electronegativity difference can be used to determine the polarity of a substance. Typically an ionic bond has an electronegativity difference of 1.8 or above, whereas a polar covalent bond is between 0.4 to 1.8, and a nonpolar covalent bond is 0.4 or below. Figure 7.1 Electronegativity Difference Diagram. The diagram above is a guide for discerning what type of bond forms between two different atoms. By taking the difference between the electronegativity values for each of the atoms involved in the bond, the bond type andpolarity can be predicted. Note that full ionic character is rarely reached, however when metals and nonmetals form bonds, they are named using the rules for ionic bonding. Substances with zero or low electronegativity difference such as H2, O2, N2, CH4, CCl4 are nonpolar compounds, whereas H2O, NH3, CH3OH, NO, CO, HCl, H2S, PH3 higher electronegativity difference are polar compounds. Typically compounds that have similar polarity are soluble in one another. This can be described by the rule: This means that substances must have similar intermolecular forces to form solutions.

How To Determine The Molarity Of A 10% Glucose Solution - Quora
How do you determine the molarity of a 10% glucose solution? Answered Aug 25, 2016 Author has 118 answers and 162.1k answer views OK, I am going to go with 10% (w/v) for the 10%. You could make a 10% (w/w), but that would make the maths difficult*. A 10% (w/v) glucose solution would be 10 g of glucose make up to 100 ml (if you are struggling with percentage solutions then check out this blog post: Calculating Percentage Solutions ). As there is 10 g in 100 ml then there will be 100 g in 1 liter. (Remember that molarity is just moles per liter.) The molecular weight of glucose is: 180.1559 g/mol The molarity is therefore: 100 / 180.1559 = 0.555 M If you are struggling with molarity then please have a look at my blog post: Why is memorising the molarity formula a bad idea? in which I go over molarity calculations. * a 10% (w/w) would be 10 g of glucose, dissolved in 90 g of water. The water would take up 90 ml (density of water is 1 g / ml), but I dont know what the final volume would be occupied by the glucose. Hence, I dont know the final volume of the solution, so I cant work out the molarity.
