Interpretation Introduction

Interpretation: The lipids that contain both ester and amide linkages has to be predicted.

Concept introduction: An organic compound found in the living organism which is soluble in nonpolar solvents but insoluble in water is known as lipid.  Lipids, also known as fats, store energy in the body.  The classification of lipids on the basis of biochemical function is as follows:

• • Energy-storage lipids. Example: triacylglycerols.
• • Membrane lipids. Examples: phospholipids, sphingolipids and cholesterol.
• • Emulsification lipids. Example: bile acids.
• • Messenger lipids. Example: steroid hormones and eicosanoids.
• • Protective-coating lipids. Example: biological waxes.
