PGAL , triose phosphate(redirected from glyceraldehyde phosphate)
PGAL (phosphoglyceraldehyde), triose phosphate or glyceraldehyde phosphatea three-carbon molecule produced from fructose diphosphate in GLYCOLYSIS. See Fig. 250 . PGAL is also a vital molecule in PHOTOSYNTHESIS, being produced in the CALVIN CYCLE from the phosphorylation and reduction of PGA by ATP and NADPH respectively which are produced in the LIGHT REACTIONS.Via a series of steps, two molecules of PGAL are rearranged to form six-carbon GLUCOSE.
