Metabolite Identification
Common NameOryzalic acid B
DescriptionOryzalic acid B, also known as oryzalate b, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Oryzalic acid B is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, oryzalic acid b has been detected, but not quantified in, cereals and cereal products. This could make oryzalic acid b a potential biomarker for the consumption of these foods.
