Identification
YMDB IDYMDB00405
NameOrotic acid
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionOrotic acid, also known as orotate or orotsaeure, belongs to the class of organic compounds known as pyrimidinecarboxylic acids. These are pyrimidines with a structure containing a carboxyl group attached to the pyrimidine ring. Orotic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Orotic acid exists in all living species, ranging from bacteria to humans. Orotic acid is a potentially toxic compound.
