Answer 1

D-glucose is the enantiomer of the L-glucose and we call it dextrose. L-glucose is an organic compound and its IUPAC name is (2S,3R,4S,5S)-2,3,4,5,6-pentahydroxyhexanal. In D-glucose, three hydroxyl groups and one hydrogen group attach to the right side whereas, in L-glucose, three hydroxyl groups and one hydrogen group attach to the left side.

Furthermore, D-glucose can exist in both linear form and cyclic form, but L-glucose exists in an equilibrium mixture of α-L-glucopyranose and β-L-glucopyranose. D-glucose is the main energy source in most of the living organisms. However, L-Glucose is a low-calorie sweetener that is a good suggestion for diabetes patients.
