Detailed explanation-1: -Lipids are key to brain structure and function; the lipids form nerve cell membranes, insulate neurons (the cables that send messages throughout the body), and help send signals within the brain. 3) Insulate and Protect – Our bodies are padded with fat, protecting us from everyday friction.

Detailed explanation-2: -Lipids are also used to insulate and protect your body. You have a layer of fat just below your skin that helps to keep your internal body temperature regular despite the external temperature. Your vital organs, such as the kidneys, have a layer of fat around them that acts like bubble wrap to protect them from injury.

Detailed explanation-3: -White adipose tissue White fat cells (adipocytes) have a simple structure composed of a single lipid droplet (fat molecule) and a few cellular organelles. They provide energy storage, insulation from extreme temperatures and cushioning around soft organs.

Detailed explanation-4: -Proteins. Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes.
