Furanosen

Furanosen is a term that does not correspond to a widely recognized chemical entity in current scientific literature. There is no entry under this name in major chemical databases such as PubChem or ChemSpider, and no standard IUPAC definition exists.

The name may be a misspelling or variant of furanose, the five-membered ring form of carbohydrates; examples include ribofuranose and fructofuranose. Alternatively, furanosen could appear as a neologism in a niche publication, a brand name, or a fictional or hypothetical compound derived from a furan ring. Without a specific context or primary source, no structural formula or properties can be established.

In biochemistry and carbohydrate chemistry, the term furanose denotes the five-membered ring form of sugars, but this does not define furanosen. If the term is encountered in a text, it should be defined by the author or traced to a cited source to avoid confusion. See also furanose and furan for related concepts and terminology.
