Detailed explanation-1: -Lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water. Lipids include: Fats and oils (triglycerides) Phospholipids.
Detailed explanation-2: -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-3: -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-4: -Waxes and Oils are lipids, having hydrophobic properties, and are derived from plants and animals. Oil is simply fat with unsaturated fatty acid chains, and is found in liquid form at room temperature.
Detailed explanation-5: -Fats are esters of fatty acids with glycerol, and are solid at, room temperature. On the other hand, waxes are esters of fatty acids other than glycerol. They contain one mole of long chain fatty acid esterified with one mole of high molecular weight monohydroxy alcohol.
