Q. 15.3 - An Introduction to General, Organic, and Biological Chemistry

Question

What are some functions of lipids in the body?

Step-by-Step Solution

Answer

Hormonal lipids function as chemical messengers.

They are the primary structural components of cell membranes.

Step 1: An Introduction

Lipids are an organic chemical class that is largely insoluble in water. Lipids are molecules that are composed mostly of carbon, hydrogen, and oxygen and are composed of fats and oils. Triacylglycerols, phospholipids, and sterols are the three primary forms of lipids. 

Step 2: Determine the functions of the lipids.

Lipids perform the following roles in the body:

They are energy-rich dietary components that offer energy while fasting.

They shield the internal organs from mechanical harm.

They keep the internal organs warm.

Hormonal lipids function as chemical messengers.

They are the primary structural components of cell membranes.
