Orotidine (Uridin-6-carboxylic acid) is a nucleoside found in bacteria, fungi, and plants. In humans, orotidine occurs as its 5'-phosphate (orotidylic acid).

Orotidine 5′-monophosphate, a pyrimidine ribonucleoside, functions as an endogenous metabolite in human, E. coli, and mouse processes. It serves as an intermediate in uridine monophosphate (UMP) biosynthesis and is utilized in researching the mechanism of orotidine 5′-monophosphate decarboxylase.
