What is GLYCOGEN? What does GLYCOGEN mean? GLYCOGEN meaning, definition & explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body. In humans, glycogen is made and stored primarily in the cells of the liver and the muscles hydrated with three or four parts of water. Glycogen functions as the secondary long-term energy storage, with the primary energy stores being fats held in adipose tissue. Muscle glycogen is converted into glucose by muscle cells, and liver glycogen converts to glucose for use throughout the body including the central nervous system. Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants. It has a structure similar to amylopectin (a component of starch), but is more extensively branched and compact than starch. Both are white powders in their dry state. Glycogen is found in the form of granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides (lipids). In the liver, glycogen can comprise from 5 to 6% of its fresh weight (100–120 g in an adult). Only the glycogen stored in the liver can be made accessible to other organs. In the muscles, glycogen is found in a low concentration (1-2% of the muscle mass). The amount of glycogen stored in the body—especially within the muscles, liver, and red blood cells—mostly depends on physical training, basal metabolic rate, and eating habits. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells. The uterus also stores glycogen during pregnancy to nourish the embryo.

Polysaccharides are carbohydrate polymers consisting of tens to hundreds to several thousand monosaccharide units. All of the common polysaccharides contain glucose as the monosaccharide unit. Polysaccharides are synthesized by plants, animals, and humans to be stored for food, structural support, or metabolized for energy. Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles. Structurally, glycogen is very similar to amylopectin with alpha acetal linkages, however, it has even more branching and more glucose units are present than in amylopectin. Various samples of glycogen have been measured at 1,700-600,000 units of glucose. The structure of glycogen consists of long polymer chains of glucose units connected by an alpha acetal linkage. The graphic on the left shows a very small portion of a glycogen chain. All of the monomer units are alpha-D-glucose, and all the alpha acetal links connect C # 1 of one glucose to C # 4 of the next glucose. The branches are formed by linking C # 1 to a C # 6 through an acetal linkages. In glycogen, the branches occur at int Continue reading >>

    I've learned that plants transform glucose into sucrose before sending it into phloem. But the process seems to be complex and energy comsuming. Why should plants do it? Is it really necessary?

    Glucose, fructose and galactose are the three dietary monosaccharides. Glucose and Fructose are simple monosaccharides found in plants. A monosaccharide is the basic unit of carbohydrate and the simplest form of sugar, glucose are aldose and Fructose are ketose.
    If the carbonyl is at position 1 (that is, n or m is zero), the molecule begins with a formyl group H(C=O)-, and is technically an aldehyde. In that case, the compound is termed an aldose. Otherwise, the molecule has a keto group, a carbonyl -(C=O)- between two carbons; then it is formally a ketone, and is termed a ketose. Ketoses of biological interest usually have the carbonyl at position 2. http://en.wikipedia.org/wiki/Monosaccharide
    Whereas Sucrose is a disaccharide composed of glucose and fructose. A disaccharide is more complex than monosaccharide, more complex compounds like oligosaccharides and polysaccharides exists. Sucrose synthesised within the cytosol of photosynthesizing cells is then available for general distribution and is commonly trans located to other carbon-demanding centers via the phloem.
    Sucrose and starch are more efficient in energy storage when compared to glucose and fructose, but starch is insoluble in water. So it can't be transported via phloem and the next choice is sucrose, being water soluble and energy efficient sucrose is chosen to be the carrier of energy from leaves to different part of the tree. Another problem exists, glucose is highly reactive and this may result in some intermediate reactions while transporting glucose. Being a complex structure, sucrose is not as much reactive as glucose. So plants uses the sucrose as a medium to transfer energy. Inside the cells, sucrose is converted back to glucose and fructose. Energy is yielded when it is needed. So plants transfer glucose and fructose in the form of sucrose in order to:
    Increase energy storage
    Efficient energy transfer
    Removing in between reactions

    there is no free glucose in the photosynthesis. Stop to spread that myth. The net product is G3P. The end products of photosynthesis are sucrose and starch, but never glucose. Do you test glucose in the leaves? No... it is always for starch. ;) The G3P is converted to sucrose and other molecules, for example, thiamine. Glyceraldehyde 3-phosphate occurs as a reactant in the biosynthesis pathway of thiamine (Vitamin B1), another substance that cannot be produced by the human body. Part of sucrose is then translocated to the phloem. Starch is stored in the stroma of chloroplasts. It is also stored in the amyloplasts in the roots, stems cells after sucrose suffers a conversion to starch.

Storage And Use Of Glucose

The glucose produced in photosynthesis may be used in various ways by plants and algae. Storage Glucose is needed by cells for respiration. However, it is not produced at night when it is too dark for photosynthesis to happen. Plants and algae store glucose as insoluble products. These include: Use Some glucose is used for respiration to release energy. Some is used to produce: Plants also need nitrates to make proteins. These are absorbed from the soil as nitrate ions. Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide. If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot. If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like t Continue reading >>

In this video I discuss the what are carbohydrates and the types of carbohydrates. The pros and cons to each type, and the best carbs to eat. Transcript Types of carbs So, what are the different types of carbohydrates? The answer to this question depends on who you ask. Some common classifications would be healthy and unhealthy, good and bad, slow and fast. In this video I am going to classify them as simple, complex and fibrous. Before we get into those classifications, we need to look at molecules. I know, fun stuff, but it will help you understand better. A monosaccharide is a single molecule, such as fructose, which is found in fruit. A disaccharide consists of 2 monosaccharide molecules, such as sucrose or table sugar. And a polysaccharide consists of many monosaccharide molecules, such as in whole grain pasta. Now that we have that out of the way, lets look at simple carbohydrates. Simple carbohydrates are made up of mono and disaccharides, 1 or 2 molecules. Some foods include, fruits, milk, and foods with high amounts of added sugars. Typically simple carbohydrates are easily absorbed into the bloodstream because of their simple molecular structure. However, when you obtain simple carbohydrates from whole foods, they are usually combined with vitamins, minerals and fiber, which slows down the digestive process. Now, lets look at complex carbohydrates. Complex carbohydrates are composed of polysaccharides, so, because of their more complex molecular structure, they can take longer for the body to break down and digest, like whole grains and vegetables. However, some complex carbohydrate foods have been processed, which strips them of some of their natural, high fiber content as well as vitamins and minerals, so they are digested faster and more easily. So, with both simple and complex carbohydrates I have mentioned fast and slow digestion. Why is that important? 3 reasons, #1 is it is going to make you feel fuller longer, rapid digestion means hunger returns quicker which leads to more consumption. #2, typically slower digested foods cause lower blood level spikes, and #3, slower, longer digestion means the body is using more energy over a longer period of time to break down the food, which is an increase or boost in metabolism. Next up is fiber. Fiber is parts of plants that cant be digested. I have a separate video that looks deeper into fiber that I will link in the little I in the upper right-hand corner of your screen. Bottom line. So, the question is what type of carbohydrates should you eat. That is actually very easy to answer. All 3 types. Don’t focus on the types, instead, focus on Carbohydrates that have been minimally processed, like whole grain pasta, and whole wheat bread, also Fruits and vegetables that contain fiber, vitamins and minerals. And of course anything from dairy queen. Ah, just joking with ya folks. Seriously though, minimize the consumption of the processed foods, if you can eliminated them great, if not, its about moderation. Its ok to eat the foods you love, you just have to do it in moderation.
