Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name INOSINE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Inosine

Inosine is a purine nucleoside in which hypoxanthine is attached to ribofuranose via a beta-N9-glycosidic bond. It has a role as a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a purines D-ribonucleoside and a member of inosines. It is functionally related to a hypoxanthine and a ribofuranose. — ChEBI
