Metabolite Identification
Common NameS-Adenosylhomocysteine
DescriptionS-Adenosylhomocysteine, also known as adenosyl-homo-cys or adohcy, belongs to the class of organic compounds known as 5'-deoxy-5'-thionucleosides. These are 5'-deoxyribonucleosides in which the ribose is thio-substituted at the 5'position by a S-alkyl group. S-Adenosylhomocysteine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. S-Adenosylhomocysteine exists in all living species, ranging from bacteria to humans. S-Adenosylhomocysteine is a potentially toxic compound.
