Detailed explanation-1: -Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.

Detailed explanation-2: -Fats and oils are part of a class of biomolecules called lipids, which are loosely defined as biomolecules that are insoluble in water but soluble in organic solvents like hexane or chloroform.

Detailed explanation-3: -Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol. Fats and oils are esters of glycerol and three fatty acids.

Detailed explanation-4: -Fats, oils, and waxes belong to the group of naturally occurring organic materials called lipids. Lipids are those constituents of plants or animals that are insoluble in water but soluble in other organic solvents.

Detailed explanation-5: -Waxes are a class of lipids that contain two monomers, one fatty acid bonded through an ester linkage to one alcohol (a hydrocarbon containing a hydroxyl group). The hydrocarbon chain in the alcohol monomer of waxes varies from a short linear chain to complex carbon ring structures.
