Thymidine
Thymidine is a molecule (known as a
nucleoside) that is formed when
thymine is attached to a
deoxyribose ring (also known as a
deoxyribofuranose) via a β-N
1-
glycosidic bond.
Thymidine can be phosphorylated with one, two or three phosphoric acid groups, creating respectively TMP, TDP or TTP (thymidine mono- di- or triphosphate).
