Concept explainers
Interpretation:
The different chirality centers of cholesterol are to be marked with an asterisk.
Concept Introduction:
>The molecules which are non-superimposable or not identical with their mirror images are known as chiral molecules.
>A pair of two mirror images which are non-identical is known as enantiomers which are optically active.
>The objects or molecules which are superimposable with their mirror images are achiral objects or molecules and these objects have a centre of symmetry or plane of symmetry.
>The achiral compounds in which plane of symmetry is present internally and consists of chiral centres are known as meso compounds, but they are optically inactive.
>Diastereomers are the stereoisomers that are not mirror images of each other and are not superimposable on each other.
>They possess different physical as well as chemical properties, because of difference in orientations.
>Cholesterol is an organic compound and a derivative of steroid. In the human body, it is produced as an intermediate in the biosynthesis of steroids. It is produced at a much higher rate than what is necessary for the synthesis of steroid. In a molecule of cholesterol, there is no internal plane of symmetry, and hence every carbon atom is different and each chiral carbon has four different groups.
