Answer:
On the attached picture.
Explanation:
Hello,
In this case, one must remember that transamination is a biochemical reaction that transfers an amino group to the carbonyl group of a ketoacid to form a new amino acid and a new ketoacid.
For this example, on the attached picture you will see the corresponding chemical reaction in which to the initial ketoacid, both the amino and an additional hydrogen are transferred from the amino acid of side chain X to form the requested α-ketoacid of side chain X.
Best regards.
