Chapter 21, Problem 38A

Interpretation Introduction

Interpretation:

The bio-molecule classified as a lipid and condition for the classification needs to be explained.

Concept introduction:

Lipid − the hydrophobic and insoluble molecules in water are termed as lipids. Lipid is consists of carbon, hydrogen, and oxygen. These substances help in maintain the structure for the cell, and storehouse of the energy. The lipids are generally classified into three categories.

Answer to Problem 38A

The insoluble fatty and oily substances are classified as lipids. The classification based on the physical property of the different types of lipids.

Explanation of Solution

Lipids are composed of carbon, hydrogen, and oxygen. These types of substances have many important biological functions. They are used as structural participants of cell membranes and energy storage sources.

The classification of the lipids based on the concept of building blocks and the ketoacyl groups and isoprene groups.

Conclusion

The fat, oily substances are classified as lipids. The macromolecules with the hydrophobic property termed as lipids.

Lipids are insoluble biomolecules, defined as non-polar property is the condition for solubility in water-based solutions.
