Somatostatin Acetate

Somatostatin, also known as growth hormone–inhibiting hormone (GHIH), is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion. Somatostatin has two active forms produced by alternative cleavage of a single preproprotein: one of 14 amino acids (shown in infobox to right), the other of 28 amino acids which is the short form with another 14 amino acids at one end.
