The Uses of DL-GLYCERALDEHYDE

DL-Glyceraldehyde has been used:

• as modifying reagent in the preparation of crystallization solution
• as a substrate to measure aldose reductase activity
• in the preparation of d/l-glyceraldehyde stock to determine the specific activity of GAPDH (glyceraldehyde 3-phosphate dehydrogenase)

The Uses of DL-GLYCERALDEHYDE

Isotope labelled Glyceraldehyde is the simplest of all aldoses and have been shown to be the one of the carbonyl metabolite of dietary fructose.

Definition

Isomeric with dihydroxyacetone. It is produced by the oxidation of sugars in the body. As the simplest aldose, the conformation of dand lglyceraldehydes has been designated the reference standard for dand l-carbohydrates and derivatives.

General Description

Glyceraldehyde is a simple monosaccharide. Based on the number of carbon atoms and the type of carbonyl group present, glyceraldehyde belongs to subgroup triose. It is a colourless and sweet compound.

Biochem/physiol Actions

Glyceraldehyde serves as an efficient cross-linking agent and is considered non-toxic. It is an intermediate of a number of metabolic such as glycolysis and pentose phosphate pathway.

Purification Methods

Crystallise it from EtOH/diethyl ether. The D(+)-
