[[碱基]]，在化学中本是“[[碱性基团]]]”的简称。有机物中大部分的碱性基团都含有[[氮原子]]，称为[[含氮碱基]]，[[氨基]]（-NH2）是最简单的含氮碱基。

碱基，在生物化学中又称[[核碱基]]、含氮碱基，是形成[[核苷]]的含[[氮化合物]]，核苷又是[[核苷酸]]的组分。碱基、核苷和核苷酸等单体构成了核酸的[[基本构件]]。

核碱基间可以形成碱基对，且彼此堆叠，所以，它们是长链螺旋结构，例如[[核糖核酸]]（RNA）和[[脱氧核糖核酸]]（DNA）的重要组成部分。

*中文名：[[碱基]]

*外文名:nucleobase

*别    名:[[核碱基]]、[[含氮碱基]]

*性    质:[[嘌呤]]和[[嘧啶]]的[[衍生物]]

*作    用:组成DNA、RNA

*种    类：腺嘌呤、鸟嘌呤、胞嘧啶、胸腺嘧啶、尿嘧啶

*构成元素：碳、氧、氢、氮

*原    则：互补原则
