嘧啶和嘌呤有什么不同

分別來(lái)介紹一下兩種物質(zhì)：

嘧啶：

嘧啶（C4H4N2，1,3-二氮雜苯）是一種雜環(huán)化合物。嘧啶（Pyrimidine）由2個(gè)氮原子取代苯分子間位上的2個(gè)碳形成，是一種二嗪。和吡啶一樣，嘧啶保留了芳香性。

名稱(chēng)：嘧啶  分子式：C4H4N2

摩爾質(zhì)量：80.09g/mol  密度：1.016g/ml

熔點(diǎn)：20-22°C     沸點(diǎn)：123-124°C

嘌呤：

嘌呤（Purine），是身體內存在的一種物質(zhì)，主要以嘌呤核苷酸的形式存在，在作為能量供應、代謝調節及組成輔酶等方面起著(zhù)十分重要的作用。

嘌呤是有機化合物，分子式C5H4N4，無(wú)色結晶，在人體內嘌呤氧化而變成尿酸，人體尿酸過(guò)高就會(huì )引起痛風(fēng)。海鮮，動(dòng)物的肉的嘌呤含量都比較高。

所以，有痛風(fēng)的病人除用藥物治療外（醫治痛風(fēng)的藥物一般對腎都有損害），更重要的是平時(shí)注意忌口。
