SIRT4 is a mitochondrial ADP-ribosyltransferase that inhibits mitochondrial glutamate dehydrogenase 1 activity, thereby downregulating insulin secretion in response to amino acids. [7] A deacetylation of malonyl-CoA decarboxylase enzyme by SIRT4 represses the enzyme activity, inhibiting fatty acid oxidation in muscle and liver cells.

α-Amanitin (alpha-Amanitin) is a cyclic peptide of eight amino acids.It is possibly the most deadly of all the amatoxins, toxins found in several species of the mushroom genus Amanita, one being the death cap (Amanita phalloides) as well as the destroying angel, a complex of similar species, principally A. virosa and A. bisporigera.
Structure of a typical L-alpha-amino acid in the "neutral" form. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2]

Norvaline (abbreviated as Nva) is an amino acid with the formula CH 3 (CH 2) 2 CH(NH 2)CO 2 H. The compound is a structural analog of valeric acid and also an isomer of the more common amino acid valine. [2] Like most other α-amino acids, norvaline is chiral. It is a white, water-soluble solid.
β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.
The catabolism of amino acids can lead to toxic levels of ammonia. Furthermore, there is a limited rate at which the gastrointestinal tract can absorb amino acids from proteins. [12] Uric acid is not a waste metabolite derived from protein metabolism, but many high protein diets also contain higher relative fractions of nucleic acids.
