 DHAP and thus glycerol 3-phosphate is also possible to be synthesized from amino acids and citric acid cycle intermediates via glyceroneogenesis pathway.It is also synthesized by phosphorylating glycerol generated upon hydrolyzing fats with glycerol kinase, and can feed into glycolysis or gluconeogenesis pathways.Glycerol 3-phosphate is a starting material for "de novo" synthesis of glycerolipids.
