1. (a) (i) Define lipids

Lipids are a diverse group of naturally occurring organic compounds that are insoluble in water but soluble in nonpolar organic solvents. They include fats, waxes, sterols, fat-soluble vitamins (such as A, D, E, and K), monoglycerides, diglycerides, phospholipids, and others. Their main biological functions involve energy storage, structural components of cell membranes, and signaling molecules.
