Description
Insulin molecule. Computer artwork of an insulin molecule, showing its secondary structure (ribbons) and central zinc atom (sphere). Insulin consists of two peptide chains, A and B, which are linked by disulphide bridges. This is the hexamer form of the hormone, containing three of each subunit. Insulin is released from the pancreas when blood sugar levels are high. Insufficient production of insulin leads to an accumulation of glucose in the blood causing diabetes.
