说明

一般描述

黄嘌呤是一种嘌呤,可经由嘌呤代谢途径通过不同前体生成:
  • 鸟嘌呤脱氨酶催化的鸟嘌呤脱氨
  • 黄嘌呤氧化还原酶催化的次黄嘌呤转化
Xanthine or its derivatives are naturally present in animal organs, yeast, potatoes, coffee beans, and tea.
 

应用

Xanthine has been used as a substrate for the determination of xanthine oxidase (XOD) inhibitory activity.[1][2] It has also been used in the following systems:
  • yeast culture[3]
  • human cell line culture
  • recombinant viruses cloned as bacterial artificial chromosomes in Escherichia coli

生化/生理作用

Xanthine and xanthine oxidase are used to generate superoxide radicals to measure the activity of superoxide dismutase.
