(a)
Interpretation: To determine whether glutamate and aspartate could function as the two reactants in a transamination reaction or not.
Concept introduction: Transamination reaction is a biochemical reaction that involves the transfer of an amino group. In transamination reaction exchange of an amino group from an

(a)

Answer to Problem 15.34EP
No, glutamate and aspartate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Glutamate is an amino acid and its structure is:
Aspartate is an amino acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Both glutamate and aspartate are amino acids thus they cannot function as reactants in a transamination reaction. For a transamination reaction to take place there must be one amino acid present along with a keto acid.
(b)
Interpretation: To determine whether aspartate and
Concept introduction: Transamination reaction is a biochemical reaction that involves the transfer of an amino group. In transamination reaction exchange of an amino group from an
The general structure of an amino acid is:
Here,
An acid containing both carbonyl and carboxyl functional group is known as a keto acid. A general representation of a keto acid is:

(c)

Answer to Problem 15.34EP
No, succinate and
Explanation of Solution
Succinate is a diacid acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid.
(d)
Interpretation: To determine whether glutarate and aspartate could function as the two reactants in a transamination reaction or not.
Concept introduction: Transamination reaction is a biochemical reaction that involves the transfer of an amino group. In transamination reaction exchange of an amino group from an
The general reaction to illustrate transamination is as follows:
The general structure of an amino acid is:
Here,
An acid containing both carbonyl and carboxyl functional group is known as a keto acid. A general representation of a keto acid is:
(d)

Answer to Problem 15.34EP
No, glutarate and aspartate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Aspartate is an amino acid and its structure is:
Glutarate is a diacid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Aspartate is an amino acid but glutarate is not a keto acid. For a transamination reaction to take place there must be one keto acid present along with an amino acid. Thus, glutarate and aspartate cannot function as the reactants in a transamination reaction.
