purine

Purine - 英汉词典内容

基本定义

Purine（嘌呤）是一种含氮的杂环有机化合物，广泛存在于生物体内，尤其是在核酸（DNA和RNA）中。它在细胞代谢中扮演重要角色，参与能量传递和信号传递。

词性分析

该词主要用作名词，表示化合物本身。没有常用的形容词形式。

词语辨析

常与嘌呤相关的词汇包括“嘧啶”（pyrimidine），后者也是一种核苷酸的重要组成部分，但结构上与嘌呤不同。

近义词

• 核苷酸（nucleotide）
• 氮杂环化合物（nitrogenous heterocycle）

反义词

在化学上，通常没有直接的反义词，但可以考虑与其他类型的生物碱或结构不同的核酸成分进行对比。

用法

在生物化学和分子生物学领域经常使用，尤其是在讨论核酸结构和功能时。
