Metabolite Identification
Common NameL-Ribulose
DescriptionL-Ribulose, also known as D-threo-pentulose or D-lyxulose, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. L-Ribulose is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). L-Ribulose exists in all living organisms, ranging from bacteria to humans.
