Web14 aug. 2024 · Figure 13.1.1: An amino acid is an organic molecule that contains an amine group, a carbonyl group, and a side chain (R), all bonded to a central carbon atom. Amino acids can be shown with or without charges. These are equivalent structures. The amine and carboxyl groups of an amino acid are both covalently bonded to a central carbon atom.

WebThis graph depicts the protonation state of glutamate as the pH changes. At a pH below the pKa for each functional group on the amino acid, the functional group is protonated. At a pH above the pKa for the functional group it is deprotonated. If the pH equals the pKa, the functional group is 50% protonated and 50% deprotonated. Attribution: Ivy ... gps wilhelmshaven
