Concept explainers
(a)
Interpretation:
Whether cholesterol is dextrorotatory or levorotatory needs to be identified.
Concept introduction:
A compound is dextrorotatory if it rotates the plane polarize light to the right or clockwise direction and it is levorotatory if the plane of polarize light rotates to left or anticlockwise.
(b)
Interpretation:
The specific rotation of the enantiomer of cholesterol needs to be determined.
Concept introduction:
Enantiomers are a part of stereoisomers. In chemistry, enantiomers are two stereoisomers that are mirror images of each other. Usually in a pair of enantiomers of a same compound one is dextrorotatory, while the other is levorotatory. As enantiomers have chiral centers, they are optical isomers.
