Chapter 5, Problem 5.69P

Interpretation Introduction

Interpretation:

Carvone is present in many essential oils. However, its two enantiomers, viz $(+)$ and $(-)$ have different odors. What does it say about the olfactory receptors that detect Carvone?

Concept introduction:

In an achiral environment, enantiomers have exactly the same physical and chemical properties. In a chiral environment, enantiomers have different physical and chemical properties. But depending upon the situation, the behavior of enantiomers can be slightly or dramatically different. Olfactory receptors are termed as smell receptors; the protein capable of connecting to odor molecules plays an important role in the sense of smell. In order to detect the smells of enantiomers of a compound, the olfactory receptors must be chiral.
