1.about the somatostatin
somatostatin (also known as growth hormone-inhibiting hormone (ghih) or somatotropin release-inhibiting factor (srif)) 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 has two active forms produced by alternative cleavage of a single preproprotein: one of 14 amino acids, the other of 28 amino acids.
2.functions:
nutritional supplement. amino acids. mainly used for amino acid infusion, due to special wettability, also used in cold cream, cosmetics. serine constitute the human body of several kinds of essential amino acid of protein a, for the construction of protein has a very important role.
