Answer:
PGALD or Phosphoglyceraldehyde is an aldehyde compound where as pyruvate is Ester derivative
Step-by-step 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.
