(b)
Answer to Problem 26.33EP
Yes, glutamate and oxaloacetate can function as the reactants in a transamination reaction.
Explanation of Solution
Glutamate is an amino acid and its structure is:
Oxaloacetate is a keto acid and its structure is:
Transamination reaction involves the exchange of an amino group from an

(c)
Answer to Problem 26.33EP
No, glutarate and glutamate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Glutarate is a diacid and its structure is:
Glutamate is an amino acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Glutamate 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 glutamate cannot function as the reactants in a transamination reaction.
(d)
Interpretation: To determine whether oxaloacetate and succinate 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:

(d)
Answer to Problem 26.33EP
No, oxaloacetate and succinate cannot function as the reactants in a transamination reaction.
Explanation of Solution
Oxaloacetate is a keto acid and its structure is:
Succinate is a diacid acid and its structure is:
The two reactants in transamination reaction are a keto acid and an amino acid. Oxaloacetate is keto acid but succinate is not an amino acid. For a transamination reaction to take place there must be one amino acid present along with a keto acid. Thus, oxaloacetate and succinate cannot function as the reactants in a transamination reaction.
