INTRODUCTION

1.4. Lipid

Lipids are organic compounds that contain hydrogen, carbon, and oxygen atoms, which form the framework for the structure and function of living cells.

These are organic compounds and nonpolar molecules, which are soluble only in nonpolar solvents and insoluble in water because water is a polar molecule. 

In the human body, these molecules can be synthesized in the liver and are found in oil, butter, whole milk, cheese, fried foods and also in some red meats.
