A 90-amino acid peptide derived from post-translational processing of pro-opiomelanocortin (POMC) in the PITUITARY and the HYPOTHALAMUS. It is the C-terminal fragment of POMC with lipid-mobilizing activities, such as LIPOLYSIS and steroidogenesis. Depending on the species and the tissue sites, beta-LPH may be further processed to yield active peptides including GAMMA-LIPOTROPIN; BETA-MSH; and ENDORPHINS.
