Detailed explanation-1: -Fats and oils are composed of molecules known as triglycerides, which are esters composed of three fatty acid units linked to glycerol.

Detailed explanation-2: -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-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 are also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acids (Figure 1).

Detailed explanation-5: -They can be found in foods such as nuts, seeds or fish. It is important not to each too much fatty or oily food. This is because small amounts of lipid-rich foods can store large amounts of energy. Eating too much fatty or oily food, whilst not getting enough exercise, may cause obesity.
