Concept introduction:
Reductive amination of α-keto acids synthesize amino acids, in which conversion of α-keto group into an
In cells, some enzymes carry out this conversion of α-keto acids into amino acids. Here, only the D-amino acids are formed.
(b)
Interpretation:
The amino acids that are obtained from the reductive amination of given metabolic intermediates in the laboratory should be given.
Concept introduction:
Reductive amination of α-keto acids synthesize amino acids, in which conversion of α-keto group into an amine group is taking place.
In laboratory, racemic mixture (both D and L-amino acids in equal amounts) of amino acids are formed.
