Fructose has 16 optical isomers.
Fructose is a simple monosaccharide, which is usually found in plants. It forms bonds with glucose molecules to form disaccharides. It has a structure similar to glucose.
Fructose molecules have 4 chiral centers of their carbon atoms. A maximum of 2ⁿ optical isomers can occur for a molecule, where 'n' is the number of chiral centers. Since there are 4 chiral centers in fructose, it should have 2⁴ = 16 optical isomers.
The names of the 16 aldohexoses or isomers of fructose are - D-allose; D-altrose; D-glucose; D-mannose; D-gulose; D-idose; D-galactose; D-talose; L-allose; L-altrose; L-glucose; L-mannose; L-allose; L-altrose; L-galactose; and L-mannose
