Question
Chapter 32, Problem 13P
Interpretation Introduction
Interpretation:
The configuration of reaction catalyzed by beta-galactosidase should be determined.
If each step proceeds with inversion of configuration, the overall stereochemistry of the mechanism should be determined.
Concept introduction:
Galactose and glucose are monosaccharide units, that undergo condensation reaction to produce lactose, a disaccharide. Further, hydrolysis of galactose by the enzyme lactase and beta-galactosidase yields back glucose and galactose. Beta-galactosidase is an enzyme which is produced by the lac operon in E. Coli.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
