Description
Molecular model of the insulin molecule, ribbon
representation. Each chain is shown in a different
colour. Insulin molecules consist of two
polypeptide chains (A and B) linked by disulphide
bonds. Insulin decreases blood glucose
concentrations, and increases cell permeability to
monosaccharides, amino acids and blood glucose
concentrations, and increases cell fatty acids.
Defects of insulin are the cause of
hyperinsulinemia and type-II diabetes mellitus.
