摘要: A PEPTIDE containing 22 amino acids has been isolated from human pituitaries and, because of its structural resemblance to the octapeptide hormones previously pig, ox and sheep similar pigment-dispersing biological activity in lower vertebrates, called β-melanocyte stimulating hormone (β MSH)1. The discovery analysis two related pituitary peptides2,3 β- γ-lipotrophin LPH γ LPH)1 which showed that comprised first 1–58 β MSH origin, 41–58 sequence both these molecules (Table 1), led Chretien Li suggest was formed by enzymatic cleavage LPH, representing intermediate compound.
