Arginine
Conditionally essential amino acid; precursor for creatine and nitric oxide synthesis

Non-protein amino acid that contributes to arginine and nitric oxide pathway context
Amino acid and the substrate of GAD and of the first step of glutathione assembly. Intracellular roles are not a requirement to eat glutamate.
Amino acid used by enterocytes. Adult trials do not show a general permeability benefit. A postinfectious IBS supplement result stays in that group.
Nonessential amino acid in collagen-rich foods. Substrate of glutathione assembly. Trials of glycine taken alone report psychiatric-symptom changes and small, high-bias sleep findings.
Amino acid condensed with homocysteine by cystathionine beta-synthase. Diet and endogenous synthesis can both supply it.
Dopamine and norepinephrine precursor; LAT1 competition with LNAAs
