phosphoglyceric acid (PGA) A 3-carbon organic acid formed during glycolysis that is the first relatively stable compound formed in the Calvin cycle after the fixation of carbon dioxide in C3 plants. The first product, an unstable 6-carbon compound, is formed when carbon dioxide combines with ribulose diphosphate.
