Biological Activity:
Orotic acid(6-Carboxyuracil) is a heterocyclic compound and an acid. It was once believed to be part of the vitamin B complex and was called vitamin B13, but it is now known that it is not a vitamin but is instead manufactured in the body by intestinal flora. Its salts, known as orotates, are sometimes used as mineral carriers in some dietary supplements, to increase their bioavailability.Lithium orotate is the most frequently used in this manner. [1]

Application
Orotic acid (OA) is an intermediate in de novo pyrimidine biosynthesis that may be used to study the specificity and kinetics of orotate phosphoribosyltransferase (OPRT) which catalyzes the reversible phosphoribosyl transfer from 5′-phospho-α-d-ribose 1′-diphosphate (PRPP) to orotic acid (OA), forming pyrophosphate and orotidine 5′-monophosphate (OMP). Orotic acid is used as a starting material for the potential commercial bioproduction of uridine 5′-monophosphate (UMP) by microbes such as Corynebacterium ammoniagenes (ATCC 6872) or Saccharomyces cerevisiae. OA may be used to study the AMPK/SREBP-1 dependent cell signaling pathway and transcription regulation mechanisms that induce hepatic lipogenesis.
