Uracil 是普遍存在的天然嘧啶衍生物，是 RNA 核酸中的四个碱基之一。

Uracil is a common naturally occurring pyrimidine found in RNA, it base pairs with adenine and is replaced by thymine in DNA. Methylation of uracil produces thymine. Uracil's use in the body is to help carry out the synthesis of many enzymes necessary for cell function through bonding with riboses and phosphates. Uracil serves as allosteric regulator and coenzyme for many important biochemical reactions.

Uracil可作为药物,也可用于药物递送。Uracil在人体和植物中,作为反应的变构调节剂和辅酶。 Uracil还在多糖的生物合成和醛糖的运输中发挥作用。Uracil可以与元素氟反应生成5 - 氟脲嘧啶,其可以抑制RNA复制酶,阻断RNA合成进而抑制癌细胞的生长。Uracil在体内可以与核糖和磷酸的结合,进而协助合成许多细胞功能所必须的酶。
