Product Introduction:
L-glucose is an organic substance with the molecular formula C6H12O6 or H-( C =O)-( CHOH) 5-H, particularly among the aldohexose monosaccharides. As the L-isomer of sugar, it is the a lot more usual enantiomer of D-glucose.
L-glucose is the enantiomer of D-glucose, a naturally occurring carbohydrate made use of in numerous cellular procedures. But L-glucose does not take place normally in greater microorganisms, yet can be manufactured in the laboratory.
L-glucose is indistinguishable from D-glucose in taste, but can not be used by the microorganism as a source of power due to the fact that it can not be phosphorylated by hexokinase, the initial enzyme in the glycolytic pathway.
Among the well-known exemptions is Burkholderia dianthus, a plant microorganism which contains the enzyme D-aldose 1-dehydrogenase, an enzyme with the ability of oxidizing L-glucose.
Like the D-isomer, L-glucose typically happens as one of 4 cyclic architectural isomers – alpha- and beta-L-glucopyranose (the most common, with a six-atom ring), as well as alpha – and also β-L-glucofuranose (has a five-atom ring).
In aqueous remedy, these isomers interconvert within hours, with the open-chain kind as an intermediate stage.

Product Usage:
L-glucose is an artificial sugar used in the synthesis of L-glucose pentaacetate, a prospective drug for the therapy of kind II diabetes mellitus. On top of that, L-glucose can be used as a colon cleanser before colonoscopy.
L-Glucose (L-(-)- Glucose) is the enantiomer of D-glucose. L-Glucose promotes food consumption, while cells can not utilize it as an energy resource due to the fact that it can not be phosphorylated by hexokinase.
L-(-)-glucose has been used in phosphate-buffered saline (PBS) solution to induce metabolic responses in S. cerevisiae. It has also been used to study the substrate competition mode of the IICB glucose transporter.
Difference Between L Glucose and D Glucose(Compare the Difference Between Similar Terms):
The letters “D” and “L” in the names of D-glucose and L-glucose represent structural differences used to distinguish glucose molecules. These two forms are called enantiomers since their molecular frameworks are mirror images of each other. As a result, the essential difference between D-glucose as well as L-glucose is their framework. The main differences are as complies with:
- Different melting points
- d-glucose: The melting point of d-glucose is 146-150°C.
- l-Glucose: The melting point of l-glucose is 153-156°C.
- Different structure
- d-glucose: The -oh on the chiral C atom of d-glucose is on the right, with open-chain structure and ring structure, with α- and β-isomers.
- l-glucose: l-glucose has 6 tautomers, 5 hydrogen bond donors, and no surface charge.
- Different stability
- d-glucose: d-glucose has good stability and exists in free state in grapes, honey, sweet fruits, animal blood, spinal fluid and lymph fluid, etc., and widely exists in the form of polysaccharide and glycoside. in nature.
- l-glucose: l-glucose is secure at normal temperature and pressure, preventing contact with oxides.
