Glyceraldehyde phosphate



(1) A chemical compound that serves as an intermediate in several central metabolic pathways in all organisms.

(2) A phosphate ester of the 3-carbon sugar glyceraldehyde and has chemical formula: C3H7O6P.

(3) A compound derived from PGA during the dark reactions of photosynthesis.


This compound is an intermediate of photosynthesis and of glycolysis and gluconeogenesis. It also is a byproduct in the biosynthesis pathway of tryptophan, an essential amino acid. It also occurs as a reactant in the biosynthesis pathway of thiamine (vitamin b1), another substance that cannot be produced by the human body.

Variants: glyceraldehydes 3-phosphate, phosphoglyceraldehyde‎ (PGAL), 3-phosphoglyceraldehyde.
Acronyms: G3P or GAP or GADP.
Synonym: triose phosphate.
See also: glycolysis.
