(2S)-2,6-diaminohexanoic acid, lysine, lysine acid, h-Lys-oh, (S)-Lysine, Aminutrin, alpha-Lysine

概览

The extra nitrogen means its charge cannot be inferred from the alpha-amino and carboxyl groups alone. Lysine can carry a positive side-chain charge in near-neutral aqueous conditions. This is a useful extension of the simple two-group zwitterion model.
