Common NameSelenohomocysteine
ClassSmall Molecule
DescriptionSelenohomocysteine 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). Selenohomocysteine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Selenohomocysteine exists in all living species, ranging from bacteria to humans. Selenohomocysteine participates in a number of enzymatic reactions, within cattle. In particular, L-Serine and selenohomocysteine can be converted into selenocystathionine through its interaction with the enzyme cystathionine beta-synthase. In addition, Selenohomocysteine and adenosine can be biosynthesized from se-adenosylselenohomocysteine through its interaction with the enzyme adenosylhomocysteinase. In cattle, selenohomocysteine is involved in the metabolic pathway called the selenoamino acid metabolism pathway.
