Metabolite Identification
Common Name5-Amino-6-(5'-phosphoribitylamino)uracil
Description5-Amino-6-(5'-phosphoribitylamino)uracil belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. 5-Amino-6-(5'-phosphoribitylamino)uracil is an extremely weak basic (essentially neutral) compound (based on its pKa). 5-Amino-6-(5'-phosphoribitylamino)uracil has been detected, but not quantified in, several different foods, such as sapodilla, kumquats, sacred lotus, Persian limes, and Cascade huckleberries. This could make 5-amino-6-(5'-phosphoribitylamino)uracil a potential biomarker for the consumption of these foods. 5-Amino-6-(5'-phosphoribitylamino)uracil is an intermediate in riboflavin metabolism. 5-Amino-6-(5'-phosphoribitylamino)uracil is the third to last step in the synthesis of 7-hydroxy-6-methyl-8-ribityl lumazine and is converted from 5-amino-6-(5'-phosphoribosylamino)uracil via the enzyme 5-amino-6-(5-phosphoribosylamino)uracil reductase (EC 1.1.1.193). It is then converted into 4-(1-D-ribitylamino)-5-amino-2,6-dihydroxypyrimidine via a hydrolase enzyme (EC 3.1.3.- ).
