A-level Chemistry/OCR (Salters)/Engineering Proteins

Engineering Proteins is the eighth unit in the Salters Advanced Chemistry course.

A ribbon diagram of the human insulin hexamer, showing two Zn2+ ions and the histidine residues that ligate them. Each insulin monomer making up the hexamer is coloured differently.
