Dihydroxyacetone (/ ˌ d aɪ h aɪ ˌ d r ɒ k s i ˈ æ s ɪ t oʊ n / ⓘ; DHA), also known as glycerone, is a simple saccharide (a triose) with formula C 3 H 6 O 3. DHA is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin.
Dihydroxyacetone phosphate (DHAP, also glycerone phosphate in older texts) is the anion with the formula HOCH 2 C(O)CH 2 OPO 3 2-. This anion is involved in many metabolic pathways , including the Calvin cycle in plants and glycolysis .
Oxidation of cytoplasmic NADH by the cytosolic form of the enzyme creates glycerol-3-phosphate from dihydroxyacetone phosphate. Once the glycerol-3-phosphate has moved through the outer mitochondrial membrane it can then be oxidised by a separate isoform of glycerol-3-phosphate dehydrogenase that uses quinone as an oxidant and FAD as a co ...
[1] [2] The simplest ketose is dihydroxyacetone ((CH 2 OH) 2 C=O), which has only three carbon atoms. It is the only ketose with no optical activity . All monosaccharide ketoses are reducing sugars , because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised , for example in the ...
D-Glyceraldehyde is an aldotriose because the carbonyl group is at the end of the chain Dihydroxyacetone is a ketotriose because the carbonyl group is the center of the chain.. A triose is a monosaccharide, or simple sugar, containing three carbon atoms.
Dehydroacetic acid, a pyrone derivative used as a plasticiser, as a fungicide, as a bactericide, and as a food preservative; Dihydroxyacetone, the active ingredient in sunless or self-tanning skincare products; 9,10-Dihydroanthracene, a form of anthracene whose center-ring carbons have been reduced; Dihydroartemisinin, an antimalarial
The presence of neurofibrillary tangles in the brain is one of the key hallmarks of Alzheimer’s disease. These irregular clumps of protein are closely associated with disease progression.
Glycerol 3-phosphate is synthesized by reducing dihydroxyacetone phosphate (DHAP), an intermediate in glycolysis. The reduction is catalyzed by glycerol-3-phosphate dehydrogenase. DHAP and thus glycerol 3-phosphate can also be synthesized from amino acids and citric acid cycle intermediates via the glyceroneogenesis pathway.
