Chapter 23, Problem 69A

Interpretation Introduction

Interpretation: To discuss the structural features and the functional groups present in cholesterol.

Concept Introduction: The structure of cholesterol can be explained based on the functional groups and also the bonds present in the cholesterol. It has a double bond as well as the hydroxy group that is present at the beta position. It plays a role in the metabolism

Answer to Problem 69A

The structural features contain the double bond, a beta hydroxy group, and the rest of the structure is made up of carbons and hydrogens.

Explanation of Solution

It is made up of a central sterol molecule made up of four hydrocarbons. The hydrogens and carbons are arranged in a circular arrangement. A chain of hydrogens and carbons is attached at the end of the molecule which is considered a hydrocarbon chain. The hydrogen is attached to the oxygen forming the hydroxyl group which is located toward the end of the structure.

Conclusion

It has a major role in metabolism and the only functional group present in the cholesterol is the alcohol group which is at the beta position. The sterol center that is present is insoluble in water.
