Metabolite Identification
Common NameL-Dihydroorotic acid
DescriptionL-Dihydroorotic acid, also known as (S)-4,5-dihydroorotate or dihydro-L-orotate, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. L-Dihydroorotic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). The (S)-enantiomer of dihydroorotic acid that is an intermediate in the metabolism of pyridine. L-Dihydroorotic acid exists in all living species, ranging from bacteria to humans. Within humans, L-dihydroorotic acid participates in a number of enzymatic reactions. In particular, L-dihydroorotic acid can be biosynthesized from ureidosuccinic acid through the action of the enzyme cad protein. In addition, L-dihydroorotic acid and quinone can be converted into orotic acid through the action of the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In humans, L-dihydroorotic acid is involved in pyrimidine metabolism. Outside of the human body, L-Dihydroorotic acid has been detected, but not quantified in, several different foods, such as american pokeweeds, prunus (cherry, plum), red huckleberries, white lupines, and shallots. This could make L-dihydroorotic acid a potential biomarker for the consumption of these foods.
