Descrição geral

Xanthine is a purine that can be produced in the purine metabolic pathway via different precursors:
  • Guanine deamination by guanine deaminase
  • Hypoxanthine conversion by xanthine oxidoreductase
Xanthine or its derivatives are naturally present in animal organs, yeast, potatoes, coffee beans, and tea.

Aplicação

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

Embalagem

1, 5, 25 g in poly bottle

Ações bioquímicas/fisiológicas

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