What is the difference between pgal and pyruvate?

PGALD or Phosphoglyceraldehyde  is an aldehyde compound where as pyruvate is Ester derivative

Explanation:

Difference between PGALD and Pyruvate

1  PGALD is the reduced from of phosphoglyceric acid where as pyruvate is the oxidized from of glucose.

2 PGALD is formed in the dark reaction of photosyntheis but pyruvate formed at the end product of glycolysis.

3  PGALD is used is in the regeneration of Ribulose bis phosphate(RUBP) where as Pyruvate is used in the formation of Acetyl CoA  and also helps in the biosynthesis of Alanine by transamination process.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
