| | D-Glyceraldehyde Usage And Synthesis |
| Description | D-(+)-Glyceraldehyde is an intermediate in carbohydrate metabolism. It is phosphorylated by triose kinase to produce D-glyceraldehyde 3-phosphate, an intermediate in glycolysis, gluconeogenesis, photosynthesis, and other metabolic pathways. | | Chemical Properties | CLEAR ORANGE SYRUP | | Uses | D-(+)-Glyceraldehyde can be utilized as a reactant in the synthesis of:
- (S)-homophenylalanine by ruthenium oxidation of a 3-amino-1,2-diol generated via coupling of an amine, and α-hydroxyaldehyde.
- β- and γ-allenols via metal-catalyzed cyclization. Allenols are used as a key precursor for the preparation of enantiopure dihydropyrans and tetrahydrooxepines.
- Isopropylidene D-glyceraldehyde intermediate, which controls the chirality in the total synthesis of prostaglandins (PGE1).
| | Uses | D-Glyceraldehyde is the simplest of all aldoses and have been shown to be the one of the carbonyl metabolite of dietary fructose. | | Definition | ChEBI: The D-enantiomer of glyceraldehyde. | | Purification Methods | enantiomer [453-17-8] is a syrup (70 + % H2O) with [] D +14o (c 2, H2O) and the dimethyl acetal has b 124-127 o/14mm and []15 +21o (c 18, H2O).
