Human growth hormone (HGH, somatotropin) is a polypeptide secreted by the anterior pituitary. It is 191 amino acids in length and has a molecular mass of approximately 22,000 daltons. Its metabolic effects are primarity anabolic. HGH promotes protein conservation and is engaged in a wide range of mechanisms for protein synthesis. It also enhances glucose transport and facilitates glycogen storage. Its cascade of growthpromoting action is mediated by another family of peptide hormones, the somatomedins. HGH measurement is primarily of interest in the diagnosis and treatment of various forms o
