Common NameInosine
DescriptionInosine, also known as hypoxanthosine or panholic-L, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Inosine exists as a solid, possibly soluble (in water), and a moderately basic compound (based on its pKa) molecule. Inosine exists in all living species, ranging from bacteria to humans. Inosine is a potentially toxic compound.
