Members of the purine group include adenine and guanine , which are constituents of the nucleic acids , and certain plant alkaloids , e . g . caffeine and theobromine 嘌呤基的成员包括腺嘌呤和鸟嘌呤，它们是核酸以及某些植物生物碱的成分，如咖啡因和可可碱。
Biochemistry ) a nitrogenous molecule , either a pyrimidine or a purine , that combines with a pentose sugar and phosphoric acid to form a nucleotide , the fundamental unit of nucleic acids 2碱基：一种含氮的分子，嘌呤碱或者是嘧啶碱，它们和戊糖还有磷酸一起构成核苷酸，核苷酸是核酸的基本结构单位。
The results showed that activated charcoal and zeolite worked much better than others , and the content of purine compounds was fallen to 85 % and 65 % respectively than control 结果表明， 100目粒度的粉末活性炭和人造沸石对啤酒中的嘌呤类物质的吸附能力很强，嘌呤类物质的含量较对照分别下降了85 %和65 % 。
5 - fu is a inhibitor for purine metabolism and able to suppress various animal tumors . it can suppress thymidine synthetase to affect dna synthesis . in addition , it can also affect rna 化疗药物: 5 - fu为嘧啶类抗代谢药，对多种动物肿瘤有抑制作用，可抑制胸腺嘧啶脱氧核甘合成镅，影响dna的生物合成，此外，还可以作用于rna 。
Uric acid is the metabolite of purine which some food items are rich in . owing to genetic predisposition , certain people are more prone to produce excess uric acid and hence gouty attack if they eat excessive purine - rich food 有些人的新陈代谢受到遗传因素影响，体内会倾向于产生过量的尿酸，再加上暴饮暴食，便很容易诱发这个痛症。
Uric acid is the metabolite of purine which some food items are rich in . owing to genetic predisposition , certain people are more prone to produce excess uric acid and hence gouty attack if they eat excessive purine - rich food 若我们在日常饮食中，进食一些含高成份嘌呤的食物，这些嘌呤在我们体内经过新陈代谢后，就会变成尿酸。
In addition to blood formation , vitamin b12 is also involved in the biosynthesis of methyl groups , and thus , has an indirect but strong impact on the synthesis of purine and pyrimidine nucleotides , which are parts of nucleic acids , the building blocks of dna 除了造血所需，维生素b12也叁与甲基的生合成，因此间接也对嘌呤嘧啶等核酸成分的合成有重大影响。
Good luck industry co . ltd , nanjing specializes in the research and productions of purine series , and in the concept of specialization and series , by the strength of doctor mentor of colleage and experts technology 2 -氯腺嘌呤, 2 -氟- 6 -氨基嘌呤,嘌呤南京祥兆工贸有限公司用“专业化系列化”的理念，依靠大学博导等专家技术力量，专门从事嘌呤系列产品的研发和生产。
Jintan haixiang chemical industry co . , ltd . mainly engages in the research and production of fine chemicals , such as medicine intermediates , pesticide intermediates and electron liquid crystal materials . we are especially good at the r & d of ketone , pyrimidine , and purine 金坛市海翔化工有限公司主要从事医药中间体、农药中间体、电子液晶材料等精细化工产品的开发和生产。
Certain foods such as offal , shellfish , and alcohol are high in purine which are metabolized to uric acid in the body . over consumption in such foods increases the chance of having gout . can gout be cured 若在日常饮食中，喜好一些含有高成份嘌呤的食物，例如动物内脏、贝壳类海产、酒类等，这些嘌呤在我们体内经过新陈代谢后，就会变成尿酸，再加上暴饮暴食，便很容易诱发这个痛症。
