What hormone is responsible for human growth?
Growth hormone
Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland.
Choh Hao Li
Choh Hao Li (sometimes "Cho Hao Li") (; April 21, 1913 – November 28, 1987) was a Chinese-born U.S. biochemist who discovered, in 1966, that human pituitary growth hormone (somatotropin) consists of a chain of 256 amino acids. In 1970 he succeeded in synthesizing this hormone, the largest protein molecule synthesized up to that time.
