Question

Consider the structure of cholesterol. Identify the number of asymmetric carbon atoms in the structure. HO

Answer 1

Asymmetric carbon atoms are those carbon atoms which are attached to four different groups.

There are 8 asymmetric carbon atoms in the given structure. The asymmetric carbon atoms are marked. I have re-draw the structure and also showing the hydrogen atoms in the structure.

This is not asymmetric as two groups (metnege) are same and 4th 7th H H H су и 3nd HOT H lot Asymmentic Carbon as attached to your different groups

The carbon atoms which are attached to two H atoms are not asymmetric carbons. Also the carbon atoms of double bond are also not asymmetric carbons because double bond means these carbon atoms are not attached to four different groups but attached to two groups.
