The chemical reactions and pathways involving amino acids, organic acids containing one or more amino substituents. The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione. The chemical reactions and pathways involving selenocysteine, an essential component of glutathione peroxidase and some other proteins. The chemical reactions and pathways involving cysteine, 2-amino-3-mercaptopropanoic acid. The chemical reactions and pathways involving homocysteine, the amino acid alpha-amino-gamma-mercaptobutanoic acid. Homocysteine is an important intermediate in the metabolic reactions of its S-methyl derivative, methionine. Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways involving sulfur amino acids. Any process that stops, prevents or reduces the frequency, rate or extent of the chemical reactions and pathways involving sulfur amino acids. Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving sulfur amino acids. The chemical reactions and pathways involving amino acids containing sulfur, comprising cysteine, homocysteine, methionine and selenocysteine. The chemical reactions and pathways resulting in the formation of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine. The chemical reactions and pathways resulting in the breakdown of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine. The chemical reactions and pathways involving methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins. The chemical reactions and pathways involving any organic compound that is weakly basic in character and contains an amino or a substituted amino group, as carried out by individual cells. 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 involving carboxylic acids, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-). The chemical reactions and pathways involving amino acids, organic acids containing one or more amino substituents, and compounds derived from amino acids, as carried out by individual cells. The chemical reactions and pathways by which individual cells transform chemical substances. The chemical reactions and pathways involving homomethionine, a non-protein amino acid synthesized from methionine via chain elongation.
