Infobox disclaimer and references

Glycerol 3-phosphate is a chemical intermediate in the glycolysis metabolic pathway. It should not be confused with the similarly named glycerate 3-phosphate or glyceraldehyde 3-phosphate.


Gylcerol 3-phosphate is produced from glycerol, the triose sugar backbone of triglycerides and glycerophospholipids, by the enzyme glycerol kinase. Glycerol 3-phospate may then be converted by dehydrogenation to dihydroxyacetone phosphate (DHAP) by the enzyme glycerol-3-phosphate dehydrogenase. DHAP can then be rearranged into glyceraldehyde 3-phosphate(GA3P) by triose phosphate isomerase(TIM), and feed into glycolysis.

The glycerol 3-phosphate shuttle is used to rapidly regenerate NAD+ in brain and skeletal muscle cells of mammals.
