Metabolite Identification
Common NameBetaine
DescriptionBetaine, also known as Bet or acidin pepsin, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Betaine exists as a solid, possibly soluble (in water), and a moderately acidic compound (based on its pKa) molecule. Betaine exists in all eukaryotes, ranging from yeast to humans. Betaine participates in a number of enzymatic reactions, within cattle. In particular, Betaine can be biosynthesized from betaine aldehyde; which is catalyzed by the enzyme Alpha-aminoadipic semialdehyde dehydrogenase. In addition, Betaine and homocysteine can be converted into dimethylglycine and L-methionine; which is catalyzed by the enzyme betaine--homocysteine S-methyltransferase 1. In cattle, betaine is involved in the metabolic pathway called the betaine metabolism pathway.
