Dictionary » P » Phosphoglyceraldehyde




(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.

Acronym: PGAL.
Synonym: glyceraldehyde 3-phosphate (G3P or GAP), triose phosphate, 3-phosphoglyceraldehyde (GADP).
See also: glycolysis.

the Calvin cycle???help please

... phosphate is primarily recycled, that's why is it called The Calvin CYCLE ..." My question is, are you saying that the triose PGL (phosphoglyceraldehyde), instead of undergoing condensation to make sucrose, is recycled to form RuBP in the Calvin cycle? I don't think so. This is ...

How many ATPs are generated in glycolysis?

... The next step is glucose to glucose 1-6 diphosphate and then the conversion to fructose 1-6 diphospohate and then breakdown in 1-3 dipohosglyceric phosphoglyceraldehyde - but I may be a bit foggy on that step. however, after this step the conversion to acetic acid results in the gain of 4 ATP's. ...

... process is called photophosphorylation) - ATP - it is producet in photophosphorylation and it is required to reduce phosphoglyceric acid (PGA) to phosphoglyceraldehyde (PGAL) and then to reconstruct ribulose bisphosphate (RuBP) - NAD is used in respiration as hydrogen carrier - NADH2 is the reduced ...

Cellular respiration in sperm cells.

G3P is often referred to as 3-phosphoglyceraldehyde (PGAL) with respect to the product of photosynthetic carbon fixation during the Calvin cycle. During plant photosynthesis, two molecules of glycerate 3-phosphate (GP, but also known as ...
