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.
Although the disaccharide maltose contains two glucose molecules, it is not the only disaccharide that can be made from two glucoses. When glucose molecules form a glycosidic bond, the linkage will be one of two types, Î± or Î², depending on whether the molecule that bonds its carbon 1 is an Î±-glucose or Î²-glucose.altose can be produced from starch by hydrolysis in the presence of the enzyme diastase. It can be broken down into two glucose molecules by hydrolysis. In living organisms, the enzyme maltase can achieve this very rapidly.
