L-Glucose CAS#921-60-8

L-(−)-Glucose is an enantiomer of the more common D-glucose. L-Glucose is not bioavailable to cells as an energy source because it cannot be phosphorylated by hexokinase. However, certain L-glucose-utilizing bacteria that contain NAD+-dependent L-glucose dehydrogenases capable of oxidizing L-glucose have been identified.

For the synthesis of L-glucose pentaacetate, a potential treatment for type 2 diabetes; It can also be used as a colon cleanser before colonoscopy.
It is used to study biological processes such as cell metabolism and sugar transport mechanism, for example, it is used as a substrate to observe the differences between D-glucose and D-glucose in cellular uptake and metabolic pathways.
