Overview

What it is

Retatrutide (LY3437943) is a synthetic, modified peptide with 39 amino acid residues. Its published structure uses a glucose-dependent insulinotropic polypeptide (GIP) backbone with non-standard amino acids and a lipid side chain.

The reference molecule contains α-aminoisobutyric acid (Aib), α-methyl-L-leucine, and a C20 fatty diacid attached through a linker at lysine-17. These structural features distinguish it from an unmodified peptide chain. This description identifies the published molecule, not an independently established structure for the supplied sample.
