HUMAN NUTRITION

Detailed explanation-1: -Waxes are a type of long chain nonpolar lipid.

Detailed explanation-2: -Their strongly hydrophobic nature allows them to function as water repellents on the leaves of some plants, on feathers, and on the cuticles of certain insects. Waxes also serve as energy-storage substances in plankton (microscopic aquatic plants and animals) and in higher members of the aquatic food chain.

Detailed explanation-3: -Biochemists often link waxes with the thin layer of fatty constituents that cover the leaves of plants or provide a surface coating for insects or the skin of animals for which primary requirements are hydrophobicity, spreadability, and chemical and metabolic stability.

Detailed explanation-4: -Three examples of organisms that have waxes are waxy-leaf plants, arthropods such as crabs and lobsters, and waterfowl.
