PGAL

Definition

Acronym for Phosphoglyceraldehyde, a chemical compound that serves as an intermediate in several central metabolic pathways in all organisms.


Supplement

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.

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

Photosynthesis Trivia

... begins soon after sundown and ends before sunrise. (C.) The five carbon sugar is constantly being regenerated. (D.) One of the end products is PGAL. (E.) The pathway used is usually a 3-carbon pathway, although a 4-carbon pathway does exist in some species. 12. The most stable form of chemical ...

Question on Calvin Cycle

I am abit perplexed about inputs and outputs of calvin cycle. A book says that it takes 6 complete calvin cycles with 6 molecules CO2 to produce 12 PGAL of which 10 are used in forming 6 RBPs and 1 glucose. However, in the diagram, they show 3 molecules of CO2 as an input. If 3 CO2 were input to ...

Amino acid synthesis [moved to microbiology thread :-) ]

Glycolysis is the main pathway..when it's converted into PGAL, then this molecule can be converted into amino acids by running the amination proceesses. I think, moving this post into Microbiology thread would be more proper since it talked about E.coli.. ...

Photosynthesis, Cellular Respiration- Conservation of Energy

I can think that 18 ATP which is consumed in Calvin cycle is not to produce glucose, but PGAL / G3P(phospoglyceraldehyde / glyceraldehyde-3-P). And, 2 molecules of G3P equals one molecule of glucose...so??:lol:
