Insulin of a Pig (Sus scrofa; PDB Code: 9INS).

Insulin is a peptide hormone formed in β-cells of the pancreas; it stimulates anabolic processes in the muscles, liver, and fatty tissues. For example, it boosts the synthesis of glycogen, fatty acids, and proteins, and promotes the uptake of glucose, some other sugars, and amino acids into muscle and fat cells. Insulin has a hypoglycaemic effect, meaning that it reduces the level of blood sugar. Insulin’s counterparts in the metabolism are glucagon and adrenalin, which signal the body that too little glucose is on hand while insulin signals an excess of glucose.
