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). L-Dihydroorotic acid exists in all living species, ranging from bacteria to humans.
