Chemical Information
NameDihydrothymine
DescriptionAn intermediate breakdown product of thymine. Dihydropyrimidine dehydrogenase catalyzes the reduction of thymine to 5, 6-dihydrothymine then dihydropyrimidinase hydrolyzes 5, 6-dihydrothymine to N-carbamyl-b-alanine. Finally, beta-ureidopropionase catalyzes the conversion of N-carbamyl-b-alanine to beta-alanine. Patients with dihydropyrimidinase deficiency exhibit highly increased concentrations of 5, 6-dihydrouracil and 5, 6-dihydrothymine and moderately increased concentrations of uracil and thymine can be detected in urine [HMDB]. Dihydrothymine is found in many foods, some of which are japanese pumpkin, sorrel, lowbush blueberry, and horseradish tree.
