A second group of neutral lipids that are of physiological importance, though they are a minor component of biological systems, are waxes. Essentially, waxes consist of a long-chain fatty acid linked through an ester oxygen to a long-chain alcohol. These molecules are completely water-insoluble and generally solid at biological temperatures. 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. Plankton apparently use the biosynthesis of waxes to adjust their buoyant density and thus their depth in the ocean. It has been suggested that a major source of petroleum found in deep-sea sediments originates from the deposition of wax-rich dead plankton over vast periods of time. Whales and many fishes also store large quantities of waxes.<\/p>\n","protected":false},"excerpt":{"rendered":"
