Chemical Information
FooDB Name5,6-dihydrouracil
Description3,4-dihydrouracil, also known as 2,4-dioxotetrahydropyrimidine or 5,6-dihydro-2,4-dihydroxypyrimidine, is a member of the class of compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 3,4-dihydrouracil is soluble (in water) and a very weakly acidic compound (based on its pKa). 3,4-dihydrouracil can be found in a number of food items such as colorado pinyon, rocket salad (sspecies), wax gourd, and boysenberry, which makes 3,4-dihydrouracil a potential biomarker for the consumption of these food products. 3,4-dihydrouracil can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine, as well as throughout most human tissues. 3,4-dihydrouracil exists in all living organisms, ranging from bacteria to humans. In humans, 3,4-dihydrouracil is involved in a couple of metabolic pathways, which include beta-alanine metabolism and pyrimidine metabolism. 3,4-dihydrouracil is also involved in several metabolic disorders, some of which include UMP synthase deficiency (orotic aciduria), dihydropyrimidinase deficiency, ureidopropionase deficiency, and carnosinuria, carnosinemia. Moreover, 3,4-dihydrouracil is found to be associated with dihydropyrimidine dehydrogenase deficiency and hypertension.
