Amino acid and polypeptide synthesis (15)

Organic chemistry: Amino acid synthesis--Gabriel synthesis; Strecker synthesis. Edman degradation. Polypeptide synthesis--Cbz (carbobenzoxy) and Boc (tert-butoxycarbonyl) amino-protecting groups; protection of the carboxy terminus via ester formation; DCC (dicyclohexylcarbodiimide) carboxy-activating reagent. An example of calculating pI and charge at a specific pH for a long polypeptide
