Theobromine, like caffeine, and also like the asthma drug theophylline, belong to the chemical group known as xanthine alkaloids.───可可碱与咖啡因、茶碱（哮喘药）一样，属于黄嘌呤生物碱家族。
Method: Xanthine- xanthine oxidase and trace element selenium were put into the human embryo articular chondrocytes culture liquid in vitro.───方法：在体外培养的人胚关节软骨细胞培养液中，加入黄嘌呤、黄嘌呤氧化酶及微量元素硒。
Uric acid (UA) is converted from xanthine, the degradation product of purine nucleotides, by the enzyme xanthine oxidase (XO).───尿酸，是嘌呤核苷酸经黄嘌呤氧化酶作用后的黄嘌呤核苷酸，再代谢所得之产物。
Results: In xanthine oxidase method, the specific activity of SOD still could be detected although SOD was inactivated.───结果：在黄嘌呤氧化酶法反应体系中，SOD灭活后依然能够检测到SOD比活力值。
Mate also contains caffeine; xanthine alkaloids (including a mood elevator and muscle relaxant found in chocolate).───这种茶还含有咖啡因和黄嘌呤生物碱（包含在巧克力中发现的情绪调节剂和肌肉松弛剂）。
The xanthine sensor provided by the invention has shorter detection time, and stable and accurate test results.───本发明提供的？？黄嘌呤传感器，检测时间缩短，测试结果稳定准确。
Xanthine oxidase is an enzyme involved in the production of uric acid.
This study aimed to explore the relationship between xanthine oxidase (XO), one of the major sources of ROS, and intestinal injury using a neonatal rat model of NEC.
An immobilization of xanthine oxidase on the surface of microelectrode has been accomplished, and thin film microsensor for the determination of hypoxanthine has been developed in this study.
Activity of SOD was detected by xanthine oxidase technique .
Nucleobases, in this case uracil and xanthine, are the components that make up two of the most important parts of any Earth-bound life form, DNA and RNA.
Xanthinuria is a rare hereditary deficiency of xanthine oxidase, which results in hypouricemia and diminished urinary uric acid excretion.
They also found hypoxanthine and xanthine, which don't factor in to DNA but are used in other biological functions.
Riboflavin, folic acid, nicotinic acid, glutathione, xanthine, and guanosine exhibited a strong antagonistic action against both rhein and emodin.
Xanthine oxidase has been found in the endothelium of capillaries by immunohistochemistry, and superoxide is generated in endothelial cell cultures.
