Description

(2R,3S,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol (CAS 7322-31-8) is the systematic IUPAC name for L-glucose (specifically, α-L-glucopyranose).

L-glucose is the enantiomer (mirror image) of the naturally abundant D-glucose. While they share identical physical properties and sweetness, human and microbial enzymes are highly stereospecific. Consequently, L-glucose cannot be metabolized by living organisms, giving it distinct functional properties.

Core Functions and Applications

Non-Caloric Sweetener: L-glucose tastes exactly like regular sugar. However, because human digestive enzymes cannot break it down and cells cannot utilize it for glycolysis, it passes through the body without releasing calories. It has been heavily researched as a zero-calorie sugar substitute for diabetes and obesity management.
Clinical Diagnostic Tool: In medical research, L-glucose serves as a non-metabolizable marker to assess gastrointestinal permeability. By measuring its recovery rate in urine, clinicians can evaluate intestinal barrier functions (e.g., leaky gut syndrome).
Non-Biodegradable Tracer: In microbiology and environmental science, it acts as a carbon source that most bacteria and fungi cannot consume. It is widely used to study fluid dynamics, matrix diffusion, or to serve as a negative control in metabolic studies.
Chiral Building Block: As a rare, high-purity chiral molecule, L-glucose is used in organic synthesis as a chiral intermediate to manufacture complex pharmaceuticals, antiviral nucleoside analogs, and glycoconjugates.
