Answer to Problem 1SAQ

Solution:

(b)

Explanation of Solution

The lipids are a diverse group of naturally occurring organic compounds and chemical components of the cell. They are characterized by their solubility in nonpolar organic solvents (e.g., ether, chloroform, acetone, and benzene) and general insolubility in water. The long alkyl chain present in the fatty acid makes it nonpolar and insoluble in water. Therefore, it is a lipid.

The multiple hydroxyl groups present in the molecule in option (a) make it polar and soluble in water. Hence, option (a) is not correct. It is a carbohydrate. The amine group, carboxylic acid group, and relatively small chain present in the molecule in option (c) make it polar and soluble in water. Hence, option (c) is not correct. It is an amino acid. The compound in option (d) is an ether and is insoluble in water and soluble in nonpolar organic solvents, but it is not found in a cell. Hence, option (d) is not correct.

Conclusion

Thus, the correct option is (b).
