Xanthosine is a rare nucleoside and results from the deamination of guanosine of RNA . It consists of β- D- ribofuranose (sugar) and xanthine . Like inosine , it is broken down into urea by the purine nucleoside phosphorylase in the purine metabolism . Xanthosine is an intermediate in the biosynthesis of theophylline found in tea leaves .
