Melanotan I retains the complete 13-residue backbone of native alpha-MSH, modified at two positions: norleucine in place of methionine at position 4, and D-phenylalanine in place of the natural L-phenylalanine at position 7.
Full sequence: Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH₂ (CAS 75921-69-6). At approximately 1,646.9 Da, it's structurally distinct from Melanotan II, which condenses a shorter core of the same backbone into a cyclic ring.
