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. It is produced for specialized research and commercial applications where chirality is a critical factor.

Unlike its natural counterpart, it is not metabolized by conventional enzymatic pathways. This unique property makes it a target ingredient for low-calorie and non-glycemic formulation work in various industries.

In pharmaceutical and nutraceutical development, it is evaluated as a non-metabolizable sugar substitute for patients requiring strict glycemic control. Biotechnology researchers use it as a chiral reference standard and substrate.

It is essential in enzyme specificity studies where distinguishing between enantiomers is necessary for experimental validity. Food technologists exploring next-generation sweetener systems incorporate it into prototype formulations.

These experts assess taste profiles and functional behavior at a small scale to determine commercial viability. Its flavoring role also extends to controlled sensory studies comparing L- and D-sugar perception.

The product is supplied primarily as a white crystalline powder in research and specialty commercial quantities. It is available under analytical and research-grade specifications through fine chemical manufacturers.

Bulk procurement options are limited compared to commodity sugars due to its specialized nature. Buyers should confirm lot-specific purity documentation when sourcing for formulation or regulatory submissions.
