Laforin Isoform creates the protein tyrosine phosphatase. It is important to maintain an appropriate amount of tyrosine because it is essential for many cellular functions The disease is caused by mutations of the EMP2A gene‚ .As a consequence‚ maintaining an appropriate level of protein tyrosine phosphorylation is essential for many cellular functions. Tyrosine-specific protein phosphatases stimulate the removal of a phosphate group attached to a tyrosine residue‚ using a cysteinyl-phosphate enzyme

colour does it turn in presence of starch and glycogen? Starch: yellow --> blue-black (amylase in starch reacts with iodine) Glycogen: yellow --> reddish-brown (due to the multi-branched component) 5) How do plants and animals store simple sugar glucose? In the form of polysaccharides. In plants‚ starch is the polysaccharide with glucose units linked by glycosidic bonds. Glycogen‚ in animals‚ is a larger polymer. 6) How do starch and glycogen differ?

Discussion of the Metabolic and Hormonal effects of Very Low Carbohydrate Diets 1.0 Summary Low carbohydrate‚ high protein diets have been raising concerns within medicine for quite some time. There is quite some conflicting evidence regarding the benefits and detrimental effects that these diets may have on metabolic and whole body health. Bone and Calcium loss – Why does a low Carbohydrate diet affect bone? Carbohydrates‚ if highly eliminated from the diet‚ are most frequently replaced with

rises‚ the heart slows down because it might damage the arteries When glucose levels in the blood are too high‚ the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen. when blood glucose level drop‚ glucagon converts glycogen to glucose‚ in order to retain homeostasis. We produce waste‚ some of which is collected in the blood‚ filtered out by the kidney and passed as urine. Structure meets function: When the physiology of an organism aids

Drug: Glucagon Generic: GlucaGen Class of medication: Hormone‚ antihypoglycemic ACTION: Glucagon is a protein secreted by pancreatic cells that causes a breakdown of stored glycogen into glucose and inhibits the synthesis of glycogen from glucose. Indications: Hypoglycemia without IV access.

(a) Glycogen‚ starch and cellulose are polymers of glucose. Suggest reasons why their structures are appropriate for their roles in nature. (b) Why are the polymer forms of starch and glycogen utilized as storage forms of glucose by living cells rather than an equivalent amount of free glucose? 10.

Being able store the glucose in the muscles is very important for the athletes endurance and performance. Athletes who are sleep deprived will experience slower storage of glycogen which will cause their energy levels to drain even faster.
