uracil

In the third chapter, first-principles electronic structure calculations were performer to study the reaction mechanisms of ribosomal peptide bond formation catalyzed by 9-methyl Guanine or 1-methyl Uracil instead of Adenine.

第三章中我们运用量子化学从头算的方法研究，利用9-甲基鸟嘌呤和1-甲基尿嘧啶来分别替代鸟嘌呤核苷和尿嘧啶核苷进行分子突变后的反应机理的模型化学研究。

This paper reports the separation and determination of cytosine, thymine, uracil, 1-hydroxyethyl-5-fluoro uracil, 1-propionyloxy uracil and 5-fluoro uracil by capillary zone electrophoresis.

本文报道毛细管区带电泳分离和测定胞嘧啶、胸腺嘧啶、尿嘧啶、羟乙基氟尿嘧啶、尿嘧啶丙酸和5-氟尿嘧啶。

DPD is the first rate-limiting enzyme in the catabolism of uracil and thymine, and affects DNA synthesis by decreasing the level of uracil and thymine, the necessary material for DNA synthesis.

DPD是尿嘧啶和胸腺嘧啶分解过程中的第一限速酶，可降低用于DNA合成的尿嘧啶和胸腺嘧啶的水平而影响DNA的合成。
