Detailed explanation-1: -Waxes are a type of long chain nonpolar lipid. Natural waxes are typically esters of fatty acids and long chain alcohols. Waxes are synthesized by many animals and plants. Animal wax esters are typically derived from a variety of carboxylic acids and fatty alcohols.

Detailed explanation-2: -The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic). As such, phospholipids are amphipathic. In the cell membrane, phospholipids are arranged in a bilayer manner, providing cell protection and serving as a barrier to certain molecules.

Detailed explanation-3: -Wax occurs in almost all vascular plants as a constituent of the cuticle, although few plants have pronounced accumulations. Wax acts as a protective coating on the epidermis of leaves, stems, and fruits, reducing desiccation or abrasion, or resisting pest attack.

Detailed explanation-4: -Answer and Explanation: Lipids that provide a water protective layer on the surface of some animals and plants are called waxes. These lipid molecules consist of a long chain fatty acid linked to a long-chain alcohol. These lipids are found on the surfaces of leaves and the cuticle of some insects.
