Dihydrouracil is an intermediate in the catabolism of
uracil
Uracil () (nucleoside#List of nucleosides and corresponding nucleobases, symbol U or Ura) is one of the four nucleotide bases in the nucleic acid RNA. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via ...

It is the base present in the
nucleoside
Nucleosides are glycosylamines that can be thought of as nucleotides without a phosphate group. A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar (ribose or 2'-deoxyribose) whereas a nucleotid ...
dihydrouridine
Dihydrouridine (abbreviated as D, DHU, or UH2) is a pyrimidine nucleoside which is the result of adding two hydrogen atoms to a uridine, making it a fully saturated pyrimidine ring with no remaining double bonds. D is found in tRNA and rRNA molec ...

Dihydrouracil oxidase
In enzymology, a dihydrouracil oxidase () is an enzyme that catalyzes the chemical reaction
:5,6-dihydrouracil + O2 \rightleftharpoons uracil + H2O2
Thus, the two substrates of this enzyme are 5,6-dihydrouracil and O2, whereas its two product ...
