Dihydrouracil is a heterocyclic organic compound with a hydrogenated Pyrimidingrundgerüst and two keto groups at positions 2 and 4 The nucleoside of dihydrouracil is the dihydrouridine (D, U H2, Uh) is present in the RNA. It forms such as uracil from a base pair with adenine.

Formation

Uracil is hydrogenated in nucleosides by the dihydropyrimidine dehydrogenase to dihydrouracil.

Properties

Dihydrouracil is a solid, with a melting temperature of 279-281 ° C.

It forms the base pairing in the RNA to adenine hydrogen bonds with two of the 4- oxo group and the N- H group.

It is eponymous for the Dihydrouracilschleife in the tRNA.

A tRNAAla from S. cerevisiae. Dihydrouracil is featured here with D.
