Growth hormone (GH) is a Protein Poly-peptide hormone. It stimulates growth and cell reproduction and regeneration in humans and other animals.
It is a 191-amino acid, single-chain Protein polypeptide hormone that is synthesized, stored, and secreted by the somatotroph cells within the lateral wings of the anterior pituitary gland.
Somatotrophin refers to the growth hormone produced natively and naturally in animals, whereas the term somatropin refers to growth hormone produced by recombinant DNA technology, and is abbreviated "rhGH" in humans.
