How a 39-residue peptide was engineered to last a week
Tirzepatide is not a natural hormone; it is a designed peptide. Its backbone borrows from GIP, but chemists added two non-natural amino acids and a long fatty-acid tail to make it survive in the body and act on two receptors at once.
This unit opens the molecule up: the sequence, the key modifications that stretch its half-life to about five days, and how its receptor binding is deliberately lopsided.
