L-fructose

L-Fructose (CAS 7776-48-9), also known as L-Arabino-2-hexulose, is the non-natural mirror-image isomer of common fructose.

Where is L-fructose used?

• Pharmaceutical and nutraceutical development: non-metabolizable sugar substitute for patients requiring strict glycemic control
• Biotechnology: chiral reference standard and substrate
• Enzyme specificity studies: distinguishing between enantiomers
• Food technology: prototype sweetener formulations, taste profiles and functional behavior at small scale
• Controlled sensory studies compare L- and D-sugar perception.

Good to know: Unlike its natural counterpart, it is not metabolized by conventional enzymatic pathways. Buyers should confirm lot-specific purity documentation when sourcing for formulation or regulatory submissions.

Commercial specifications

• Bulk procurement options limited compared to commodity sugars
