Dihydrouracil has been used as a standard for ureido group in the colorimentric assay of transfer ribonucleic acid (tRNA).
5,6-Dihydrouracil acts as an intermediate in the catabolism of uracil.
ChEBI: 5,6-dihydrouracil is a pyrimidine obtained by formal addition of hydrogen across the 5,6-position of uracil. It has a role as a metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is functionally related to a uracil.
Dihydrouracil (DiHU) is a minor base found in transfer ribonucleic acid (tRNA). It is similar to uracil with the only exception that the C5-C6 bond is saturated. It crystallized in the monoclinic system with space group P21/C. Its crystalline structure has been analyzed. Its generation from L-cysteine and uracil via photochemical addition has been described.
