Wax ester
（重定向自Wax esters）
A wax ester (WE) is an ester of a fatty acid and a fatty alcohol.
Wax esters are formed by combining one fatty acid with one fatty alcohol molecule. Alcohols have a hydroxyl (HO-) group. Organic acids have a carboxyl (-COOH) group. Alcohols and organic acids join to form esters. In wax esters, the hydroxyl groups of the fatty alcohols joins the carboxyl groups of the fatty acids to form ester bonds.
