Glyceraldehyde (glyceral ) is a triose monosaccharide with chemical formula C 3 H 6 O 3 aldoses . It is a sweet , colorless, crystalline solid that is an intermediate compound in carbohydrate metabolism . The word comes from combining glycerol and aldehyde , as glyceraldehyde is glycerol with one alcohol group oxidized to an aldehyde.
Structure [ edit ]
Glyceraldehyde has one chiral center and therefore exists as two different enantiomers with opposite optical rotation:
In the D/L D Dexter meaning "right", or L Laevo meaning "left"
In the R/S nomenclature , either R from Latin Rectus meaning "right", or S from Latin Sinister meaning "left"
While the optical rotation of glyceraldehyde is (+) for R S empirically (by experiment).
It was by a lucky guess that the molecular D- X-ray crystallography in 1951.[2]
Nomenclature [ edit ]
In the D/L [3] R last stereocentre, for example C5 in glucose , are assigned the stereo-descriptor D- S L-
Chemical synthesis [ edit ]
Glyceraldehyde can be prepared, along with dihydroxyacetone , by the mild oxidation of glycerol , for example with hydrogen peroxide [4] ferrous salt as catalyst .[citation needed
Its cyclohexylidene acetal can also be produced by oxidative cleavage of the bis(acetal) of mannitol .[5]
Biochemistry [ edit ]
The enzyme glycerol dehydrogenase (NADP+ ) has two substrates, glycerol and NADP+ , and 3 products, D-glyceraldehyde, NADPH and H+ .[6]
The interconversion of the phosphates of glyceraldehyde (glyceraldehyde 3-phosphate ) and dihydroxyacetone (dihydroxyacetone phosphate ), catalyzed by the enzyme triosephosphate isomerase , is an intermediate step in glycolysis .
