基本信息编辑
简写为C。核酸中嘧啶型碱基之一。存在于DNA和RNA中。在植物DNA中,除胞嘧啶
外,还有少量的5-甲基胞嘧啶。在DNA的双股螺旋中,一股链上的胞嘧啶与另一股链上的鸟嘌呤配对,分子间形成三个氢键。这种碱基互补对之间的氢键是DNA双螺旋结构稳定性的重要作用力之一。胞嘧啶核苷、胞嘧啶核苷酸均可作为升高白细胞的药物。可由二巯基尿嘧啶、浓氨水和氯乙酸为原料合成制得。

Basic information editing
Shorthand for C. One of the nucleic acid type of pyrimidine bases. Found in DNA and RNA. In the plant DNA, in addition to cytosine
, there are a small amount of 5 - methyl cytosine. In the double helix of DNA, a chain of cytosine and guanine pairs of another chain, form three hydrogen bonds between the molecules. The hydrogen bonds between the complementary bases on is one of the important forces of the stability of the DNA double helix structure. Cytosine nucleoside, cytosine nucleotides can be as the drugs increased leukocyte. Can be made of 2 thiol uracil, chloroacetic acid and ammonia as raw materials synthesis.
