4) what is the difference between a hi gi carbohydrate and a low gi carbohydrate
Glycemic index Foods with carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream tend to have a high GI; foods with carbohydrates that break down more slowly, releasing glucose more gradually into the bloodstream, tend to have a low GI. The concept was developed by Dr. David J. Jenkins and colleagues[10] in 1980â€“1981 at the University of Toronto in their research to find out which foods were best for people with diabetes. A lower glycemic index suggests slower rates of digestion and absorption of the foods' carbohydrates and can also indicate greater extraction from the liver and periphery of the products of carbohydrate digestion. A lower glycemic response usually equates to a lower insulin demand but not always, and can improve long-term blood glucose control[11] and blood lipids. The insulin index is also useful for providing a direct measure of the insulin response to a food.
Polysaccharide Natural saccharides are generally of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. Examples of monosaccharides are glucose, fructose, and glyceraldehyde.[4] Polysaccharides, meanwhile, have a general formula of Cx(H2O)y where x is usually a large number between 200 and 2500. When the repeating units in the polymer backbone are six-carbon monosaccharides, as is often the case, the general formula simplifies to (C6H10O5)n, where typically 40≤n≤3000.
Citric acid cycle Products of the first turn of the cycle are one GTP (or ATP), three NADH, one QH2, and two CO2.
Dividend yield Its reciprocal is the Price/Dividend ratio.
Glycogen After a meal has been digested and glucose levels begin to fall, insulin secretion is reduced, and glycogen synthesis stops. When it is needed for energy, glycogen is broken down and converted again to glucose. Glycogen phosphorylase is the primary enzyme of glycogen breakdown. For the next 8â€“12 hours, glucose derived from liver glycogen is the primary source of blood glucose used by the rest of the body for fuel.
Diagonalizable matrix Note that the above examples show that the sum of diagonalizable matrices need not be diagonalizable.
