BIOMOLECULES AND ENZYMES

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). As such, phospholipids are amphipathic.

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. Triglycerides (see Fig. 37.3) comprise three fatty acids esterified with a glycerol backbone. ‘Triacylglycerols’ is the correct chemical name but they are more commonly known as ‘triglycerides’ and this term will be used throughout this chapter.

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.
