We can't live on air and sunshine alone. The human body needs food and water to survive. A human can go for more than three weeks without food (Mahatma Gandhi survived 21 days of complete starvation), but water is a different story. At least 60% of the adult body is made of it and every living cell in the body needs it to keep functioning.
Scheme demonstrating the function of glycogen branching enzyme. In glycogen, every 10 to 14 glucose units, a side branch with an additional chain of glucose units occurs. The side chain attaches at carbon atom 6 of a glucose unit, an Î±-1,6-glycosidic bond. This connection is catalyzed by a branching enzyme, generally given the name Î±-glucan branching enzyme. A branching enzyme attaches a string of seven glucose units (with some minor variation to this number) to the carbon at the C-6 position on the glucose unit, forming the Î±-1,6-glycosidic bond.
The glucose which is not used immediately is stored in the form of glycogen in the liver and muscles by the process of glycogenesis. Some tissues like liver and skeletal muscle store glucose in a form of glycogen which can be rapidly mobilized.lycogen consists of long polymer chains of glucose units which are bonded by an alpha acetal linkage. An acetal linkage forms by the combination of carbonyl group and alcoholic group. If the carbonyl group is an aldehyde group (-CHO), it termed as hemiacetal and if there is ketonic group, it forms hemiketal bond.
