Thymidine monophosphate


Thymidine monophosphate, also known as thymidylic acid, deoxythymidine monophosphate, or deoxythymidylic acid, is a nucleotide that is used as a monomer in DNA. It is an ester of phosphoric acid with the nucleoside thymidine. dTMP consists of a phosphate group, the pentose sugar deoxyribose, and the nucleobase thymine. Unlike the other deoxyribonucleotides, thymidine monophosphate often does not contain the "deoxy" prefix in its name; nevertheless, its symbol often includes a "d". Dorland’s Illustrated Medical Dictionary provides an explanation of the nomenclature variation at its entry for thymidine.
As a substituent, it is called by the prefix thymidylyl-.
