Concept explainers
(a)
Interpretation: To characterize oxaloacetate as a possible reactant, product, or enzyme involved in transamination, oxidative deamination, or both transamination and oxidative deamination.
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 biochemical reaction in which an
A general oxidative deamination reaction is as follows:
(a)
Answer to Problem 15.46EP
Oxaloacetate can function as a product both in transamination reaction oxidative deamination reactions.
Explanation of Solution
Oxaloacetate is a keto acid. In both transamination and oxidative deamination reaction exchange of an amino group from an
Oxaloacetate is a corresponding keto acid of aspartate. Both of them have the same carbon skeleton. Aspartate gives oxaloacetate product in both transamination and oxidative deamination reaction.
(b)
Interpretation: To characterize aspartate as a possible reactant, product, or enzyme involved in transamination, oxidative deamination, or both transamination and oxidative deamination.
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 biochemical reaction in which an
A general oxidative deamination reaction is as follows:
(b)
Answer to Problem 15.46EP
Aspartate acts as a reactant in transamination reaction.
Explanation of Solution
