Detailed explanation-1: -Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic).

Detailed explanation-2: -Triglycerides. A fat molecule is a type of lipid that consists of three fatty acid molecules connected to a 3 carbon glycerol backbone, as shown on the right. The three fatty acids can be different from one another.

Detailed explanation-3: -Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Triglycerides are the main constituents of vegetable fat and body fat in humans and other animals.

Detailed explanation-4: -One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids.

Detailed explanation-5: -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.
