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

Detailed explanation-3: -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-4: -The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails. The tails are usually fatty acids, and they can differ in length (they normally contain between 14 and 24 carbon atoms).

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.
