What it is

A 13-amino-acid hormone that drives skin pigmentation and calms inflammation; afamelanotide (Melanotan I) is an analog.

Type: Peptide hormone.

Definition (National Library of Medicine)

“A 13-amino acid peptide derived from proteolytic cleavage of adrenocorticotropic hormone, the N-terminal segment of ACTH. ACTH (1-13) is amidated at the C-terminal to form ACTH (1-13)nh2 which in turn is acetylated to form alpha-msh in the secretory granules. Alpha-msh stimulates the synthesis and distribution of melanin in melanocytes in mammals and melanophores in lower vertebrates.”
