The chemical reactions and pathways involving amino acids, organic acids containing one or more amino substituents. The chemical reactions and pathways resulting in the breakdown of ornithine, an amino acid only rarely found in proteins, but which is important in living organisms as an intermediate in the reactions of the urea cycle and in arginine biosynthesis. The chemical reactions and pathways resulting in the breakdown of ornithine, via the intermediate proline. The chemical reactions and pathways resulting in the breakdown of ornithine by decarboxylation. The chemical reactions and pathways involving ornithine, an amino acid only rarely found in proteins, but which is important in living organisms as an intermediate in the reactions of the urea cycle and in arginine biosynthesis. The chemical reactions and pathways resulting in the breakdown of any organic compound that is weakly basic in character and contains an amino or a substituted amino group. Amines are called primary, secondary, or tertiary according to whether one, two, or three carbon atoms are attached to the nitrogen atom. The chemical reactions and pathways resulting in the breakdown of amino acids, organic acids containing one or more amino substituents. The chemical reactions and pathways resulting in the breakdown of carboxylic acids, any organic acid containing one or more carboxyl (-COOH) groups.
