Summary

Description
Brain peptide responsible for activation of prothoracic glands to produce ecdysone in insects.
Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
Subunit
Heterodimer of a B chain and an A chain linked by two disulfide bonds.
Miscellaneous
Silk worm has two kinds of PTTH: 4K-PTTH and 22K-PTTH; there are many forms of 4K-PTTH.
Silk worm has two kinds of PTTH: 4K-PTTH and 22K-PTTH; there are four forms of 4K-PTTH.
Similarity
Belongs to the insulin family.
