Descripción

General description

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.

Application

Dihydrouracil has been used as a standard for ureido group in the colorimentric assay of transfer ribonucleic acid (tRNA).
