Thymidine (dT) or pyrimidine deoxyriboside (deoxynucleoside) is a pyrimidine nucleoside that is composed of the pyrimidine base thymine attached to the sugar deoxyribose which is used to synthesize DNA and the T-loop of transfer RNA upon sequential phosphorylation to deoxythymidine triphosphate (dTTP). As a constituent of DNA, thymidine pairs with deoxyadenosine (A) in the structure of double-stranded DNA.

Thymidine kinase (TK, EC is an enzyme that catalyses the phosphorylation of deoxythymidine to deoxythymidine monophosphate with a phosphate derived from ATP. Hence, dT may be used to study the distribution, specificity and kinetics of a family of thymidine kinase(s). It derives from a thymine and has a role as a metabolite (human metabolite, Escherichia coli metabolite and mouse metabolite). It is also used as a synchronizer of the cells in S phase of mitosis.
