Summary Introduction

To review:

The differences between phospholipids and triglycerides on the basis of location and body function.

Introduction:

Lipids are polymeric biomolecules. On the basis of structure, function, and location, they are categorized as triglycerides, phospholipids, and steroids. Esters of glycerol and fatty acids are called glycerides. Glycerol is a polar molecule that contains three hydroxyl groups, and fatty acid is a carboxylic acid with a long hydrocarbon chain. The fatty acid chain varies in length, which is responsible for various kinds of fats. On the basis of the number of carbon–carbon bonds, they are either saturated or unsaturated fats.
