Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids.

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.

Nov 23, 2024 · 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.

Nov 12, 2019 · Waxes Definition: Waxes are the organic compounds composed of lipophilic compounds and malleable solids. Waxes form the protective coating by the mixture of long-chain apolar lipids . In plants , wax forms a protective coat of cutin on plants , leaves , and fruits.

Waxes are esters of long-chain fatty acids with long-chain monohydric alcohols (one hydroxyl group). The carboxylic acid and the alcohol typically each have an even number of carbons. Cetyl palmitate is a typical wax, it is the ester of cetyl alcohol ( CH 3 (CH 2 ) 15 OH) and palmitic acid (CH 3 (CH 2 ) 14 COOH).

May 11, 2021 · Waxes are esters of fatty acids with long chain monohydric alcohols (one hydroxyl group). Natural waxes are often mixtures of such esters, and may also contain hydrocarbons. Plant waxes on the surfaces of leaves, stems, flowers, and fruits protect the plant from dehydration and invasion by harmful microorganisms.

Explore the diverse world of waxes, from their chemical composition to ecological roles and industrial applications. Learn about the methods for analyzing and identifying waxes, including mass spectrometry and infrared spectroscopy.

Waxes: Waxes are protective compounds. They provide a waterproof barrier in plants and animals. In plants, waxes reduce water loss and protect against pathogens. In animals, waxes protect feathers, fur, or exoskeletons from moisture …

Simple esters are made from an organic acid and an alcohol. The ester functional group is of primary importance in the biochemical group of compounds called waxes, triglycerides, and phospholipids. The simplified reaction reveals the process of breaking some bonds and forming the ester and the by product, water.
