Metabolite Identification
Common NameThymidine
DescriptionThymidine, also known as deoxythymidine or DTHD, belongs to the class of organic compounds known as pyrimidine 2'-deoxyribonucleosides. Pyrimidine 2'-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Thymidine is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Thymidine exists in all living species, ranging from bacteria to humans. Thymidine participates in a number of enzymatic reactions, within cattle. In particular, Thymidine can be biosynthesized from 5-thymidylic acid through its interaction with the enzyme cytosolic purine 5'-nucleotidase. In addition, Thymidine can be converted into 5-thymidylic acid; which is catalyzed by the enzyme thymidine kinase, cytosolic. In cattle, thymidine is involved in the metabolic pathway called the pyrimidine metabolism pathway. Thymidine is a potentially toxic compound.
