Uracil（Cat No.:A000678）is one of the four nucleobases found in RNA, where it pairs with adenine through two hydrogen bonds. As a pyrimidine derivative, it replaces thymine (found in DNA) and plays a key role in RNA’s structure and function. Uracil is involved in several biological processes, including enzymatic reactions and regulation of gene expression. It is also a precursor in the synthesis of cofactors like UDP-glucose and vitamins such as thiamine. Due to its simplicity, uracil is studied in prebiotic chemistry as a potential building block of early life.
