Web4 apr. 2024 · Each of the above standard 20 aminos have one hydrogen atom, and two groups attached to its alpha carbon atom: an amino or amine group (~NH3+) and a carboxyl group (~COOH). They are each then distinguished from other types of amino acids by their third attached functional group: side chains referred to as R groups. WebThese 7 amino acids are able to donate or accept protons to facilitate reactions as well as to form ionic bonds.
