Structural Formula Vector Image
Title: Lipotropic Hormone
CAS Registry Number: 9035-55-6
CAS Name: Lipotropin
Additional Names: pituitary lipotropic hormone; lipid-mobilizing hormone; adipokinetic hormone; lipolytic hormone; lipotrophin; LPH
Literature References: Hypophyseal hormone which stimulates the release of fatty acids from adipose tissue. b-LPH is a single chain polypeptide containing 89-93 amino acid residues and has been proposed as the biosynthetic precursor for b-MSH and b-endorphin, q.q.v., see M. Chretien et al., Can. J. Biochem. 57, 1111 (1979). g-LPH consists of 58 amino acids and is identical to the sequence of the first 58 residues of b-LPH. Both contain sequences common to ACTH and b-melanotropin, q.q.v. Sequences differ slightly among mammalian species. Isoln and proposed structure of ovine b-LPH: C. H. Li, Nature 201, 924 (1964); Y.
