Question

3) For the de novo synthesis of the amino acids:

a) Which 10 amino acids are derived from the citric acid cycle intermediates -ketoglutarate and oxaloacetate?

b) Which nine amino acids are derived from the glycolytic intermediates 3-phosphoglycerate, PEP and pyruvate?

c) Which amino acid is derived by consequence of pentose phosphate pathway?

Answer 1

Answer (A) ten amino acid derived from citric acid cycle intermediate ketoglutarate and oxaloacetate are aspartate, glutamate, proline,methionine, aspargine, glutamine, arginine, lysine glutamic acid and threonine.

Answer B nine amino acids derived from the glycolytic intermediates 3-phosphoglycerate, PEP and pyruvate are serine, isoleucine, leucine, valine alanine, tryptophan, phenylalanine, tyrosine. Glycine

Answer c amino acid from Pentose phosphate pathway. Is histidine.
