WebDihydropyrimidine dehydrogenase is involved in the first step of the breakdown of pyrimidines. This enzyme converts uracil to another molecule called 5,6-dihydrouracil and converts thymine to 5,6-dihydrothymine. The molecules created when pyrimidines are broken down are excreted by the body or used in other cellular processes. hurley hospital cafeteria hours
