Chapter 23, Problem 70A

Interpretation Introduction

Interpretation:

The location and form of fatty acids stored in human body should be determined.

Concept introduction:

The molecules which contains hydrocarbons and not soluble in water but soluble in nonpolar solvents is known as lipid.

Lipids are classified as:

Triglycerides, Phospholipids and, Steroids and Waxes.

The building blocks of fat in our bodies and in food are known as fatty acids. Fatty acid consists of carboxylic acid with long aliphatic chain which can be saturated or unsaturated.

Explanation of Solution

Fatty acid consists of carboxylic acid with long aliphatic chain which can be saturated or unsaturated. Generally, fatty acids exist as: phospholipids, triglycerides and cholesteryl esters. These are important structural components for cells.

Fats and oils consist of molecules known as triglycerides (contain ester bonds).

In human body, fatty acids are stored in cell known as adipocytes and these are stored in the form of triglycerides. The type of lipid found in our blood is known as triglycerides.
