Question
Which of the following ketoacids cannot be directly transaminated to give amino acids?Group of answer choicesoxaloacetateα-ketogluteratepyruvateb and call of the above
Solution
To determine which of the ketoacids cannot be directly transaminated to give amino acids, we need to analyze each option:
-
Oxaloacetate: Oxaloacetate can be transaminated to give aspartate, which is an amino acid. Therefore, oxaloacetate can be directly transaminated to give an amino acid.
-
α-ketogluterate: α-ketogluterate can be transaminated to give glutamate, which is an amino acid. Therefore, α-ketogluterate can be directly transaminated to give an amino acid.
-
Pyruvate: Pyruvate can be transaminated to give alanine, which is an amino acid. Therefore, pyruvate can be directly transaminated to give an amino acid.
Based on the analysis, all of the given ketoacids (oxaloacetate, α-ketogluterate, and pyruvate) can be directly transaminated to give amino acids. Therefore, the correct answer is "b and c, all of the above."
