Common Name7-Methylxanthosine
Description7-methylxanthosine is a member of the class of compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. 7-methylxanthosine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 7-methylxanthosine can be found in arabica coffee, which makes 7-methylxanthosine a potential biomarker for the consumption of this food product.
