C6H12O6 is a molecular formula and could refer to any of the following: Hexoses, Allose, Altrose, Fructose, Galactose, Glucose, Gulose, Idose, Mannose, Psicose, Sorbose, Tagatose, Talose, Inositol, how the atoms are arranged determines what the molecule is

There are several monosaccharides with six carbons. Some examples (and best known) are: Glucose, Galactose and Fructose. Other six-carbon monosaccharides are: Allose, Altrose, Mannose, Gulose, Idose, Talose, Sorbose, Tagatose, etc.

Sucrose is C12H22O11.

C6H12O6 could refer to:

* Hexoses ** Allose ** Altrose ** Fructose ** Galactose ** Glucose ** L-Glucose ** Gulose ** Idose ** Mannose ** Psicose ** Sorbose ** Tagatose ** Talose * Inositol * D-chiro-inositol

Answer 8 D-isomers of fructose, as I figured out.

Of the D-keto-hexoses (like fructose) there are :

8x D-2-ketoses: alpha and beta form of 4 members [D-psicose, D-fructose, D-sorbose, D-tagatose]

Not: D-3-ketoses can NOT form furanose ring (4C + O)

Not: D-4-ketoses = same as D-3-ketose

Not: D-5-ketoses = D-2-ketose

At last you can also mention the same set of the (full) enantiomers in L-form:

8x L-2-ketoses: alpha and beta form of [L-psicose, L-fructose, L-sorbose, L-tagatose]
