Insulin: Discovery in 1921, Structure, and Key Properties
Insulin, discovered by Banting and Best in 1921, evolved from animal pancreas extracts to highly pure recombinant human versions exceeding 98% purity. This 51-amino acid hormone features two chains linked by disulfide bonds and forms hexamers with zinc for storage and stability. Modern formulations include phenolic preservatives that trigger a conformational shift, alongside agents for isotonicity and buffering, matching natural secretion patterns of 60-80 μU/mL post-meal peaks and 5-15 μU/mL basal levels.
