It also covers waxes, which are natural esters used for waterproofing in plants and animals, mentioning common types like beeswax and lanolin, and their applications in human products such as floor polish and car wax.

It explains condensation reactions, specifically how amino acids form dipeptides, and outlines esterification, which creates esters from alcohols and carboxylic acids. Additionally, it defines saponification as the alkaline hydrolysis of esters to produce soap.
