Wax ester - Wikipedia
A wax ester (WE) is an ester of a fatty acid and a fatty alcohol. Wax esters are the main components of three commercially important waxes: carnauba wax, candelilla wax, and beeswax. [1] Wax esters are formed by combining one fatty acid with one fatty alcohol: Some wax esters are saturated, and others contain unsaturated centers.

Wax Esters: Esters of long chain fatty acid with long chain fatty alcohol give rise to wax esters. These lipids are found in microorganism, animal and plant tissues and play an important role in waterproofing, they also serve as energy reserves in marine organisms.

A wax is a fatty material that consists of a long hydrocarbon chain, with or without a functional group. Common functional groups found in waxes include alcohol, ketone, aldehyde, and ester. One of the groups of highest interest for industrial and potential food applications is the ester.

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).

2021年9月1日 · Wax esters (WE) are neutral lipid compounds composed of fatty acids esterified to long-chain fatty alcohols. Physicochemical properties and applications of WE vary due to the number of the carbon atoms of the fatty acid and the fatty alcohol moieties as well as the degree of the unsaturation that affects melting temperature, oxidation, and ...
