molecular engineering and pharmacokinetics

The three modifications that turned a fleeting hormone into a weekly medicine.

engineering a longer half-life

This unit covers the three key structural modifications that distinguish semaglutide from native GLP-1: amino acid substitutions for DPP-4 resistance, C-18 fatty diacid side chain for albumin binding, and the pharmacokinetic profile that enables both weekly injection and daily oral formulations.
