The study by Jung et al . further confirms earlier results demonstrating that dihydroxyacetone in combination with dimethylisosorbide enhances the process of ( sun-based ) tanning.
32.
At equilibrium the aldose and ketose form a mixture which in the case of the glyceraldehyde and dihydroxyacetone is also called "'glycerose " '.
33.
Cytosolic Glycerol-3-phosphate dehydrogenase ( GPD1 ), is an NAD +-dependent enzyme that reduces dihydroxyacetone phosphate to glycerol-3-phosphate.
34.
An especially high abundance can be observed for enzymes called MOX ( methanol oxidase ), FMDH ( formate dehydrogenase ), and DHAS ( dihydroxyacetone synthase ).
35.
When pyruvate of lactate is used as the precursor for glycerol 3-phosphate, glyceroneogenesis follows exactly the same pathway as gluconeogenesis until it generates dihydroxyacetone phosphate.
36.
So before glycerol can enter the pathway of glycolysis it must be converted into an intermediate molecule, which in this case is dihydroxyacetone phosphate ( DHAP ).
37.
Glycerol 3-phosphate is then oxidized to dihydroxyacetone phosphate, which is, in turn, converted into glyceraldehyde 3-phosphate by the enzyme triose phosphate isomerase.
38.
A potential weakness of these routes is the generation of enantioenriched glyceraldehyde, or its 3-phosphate derivative ( glyceraldehyde prefers to exist as its keto tautomer dihydroxyacetone ).
39.
In fructolysis, the enzyme fructokinase initially produces fructose 1-phosphate, which is split by aldolase B to produce the trioses dihydroxyacetone phosphate ( DHAP ) and glyceraldehyde.
40.
In mammalian and yeast cells, two different pathways are known for the de novo synthesis of PA, the glycerol 3-phosphate pathway or the dihydroxyacetone phosphate pathway.
