Task 5) - Explore and explain the main features involved in the anabolic metabolism of carbohydrate (glycogenisis), lipid metabolism (triglyceride storage, transport and ketosis) and protein metabolism (transamination and deamination).

Anabolic metabolism is the building of larger molecules from smaller ones, for example building monosaccharides to form carbohydrates; fatty acids and glycerol to form lipids and amino acids to form proteins. They are generally condensation reactions, producing water as two molecules join together to make a larger molecule.

All living cells must metabolise to produce vital energy that is required for active processes, this requires glucose. The normal glucose level is 90mg of glucose in 100cm3 of blood it is essential that this level remains and the body controls this in two ways, the breakdown of products to form glucose and synthesis of larger molecules from glucose in order that it be stored. Glycogenisis is the conversion of glucose into glycogen which can then be stored in the liver and muscles. When there is an excess of glucose in the body, the pancreas produces insulin, which converts glucose to glucose - 6 - phosphate and ultimately to glycogen.
