Metabolite Identification
Common NameSe-Adenosylselenohomocysteine
DescriptionSe-Adenosylselenohomocysteine belongs to the class of organic compounds known as 5'-deoxyribonucleosides. These are nucleosides in which the oxygen atom at the 5'position of the ribose moiety has been replaced by another atom. The nucleobases here are limited to purine, pyrimidine, and pyridine derivatives. Se-Adenosylselenohomocysteine is a very strong basic compound (based on its pKa). Within humans, se-adenosylselenohomocysteine participates in a number of enzymatic reactions. In particular, se-adenosylselenohomocysteine can be converted into selenohomocysteine and adenosine through its interaction with the enzyme adenosylhomocysteinase. In addition, se-adenosylselenohomocysteine can be biosynthesized from se-adenosylselenomethionine; which is mediated by the enzyme methyltransferase-like protein 6. In humans, se-adenosylselenohomocysteine is involved in selenoamino acid metabolism.
