Question
Chapter 27.3, Problem 11P
Interpretation Introduction
Interpretation: The stepwise sequence to resolve the racemic mixture of leucine enantiomers into optically active amino acids using
Concept introduction: Racemic mixture is a mixture of enantiomers in equal amounts. It is optically inactive. Racemic mixture can be resolved by the conversion of enantiomers into diastereomers.
