Clinical Significance: a-Melanocyte Stimulating Hormone is a 13 amino acid peptide produced from metabolism of Proopiomelanocortin. One of the fragments of Proopiomelano-cortin is Adrenocorticotropin which is further fragmented to form a-Melanocyte Stimulating Hormone and Corticotropin-Like Intermediate Lobe Peptide (CLIP).
