The fatty acids and fatty alcohols of wax esters from different marine animals show major differences. Wax esters of sperm whales contain C12 fatty acids and C14 fatty acid and alcohols. Monounsaturated C18 is the dominant fatty acid of most fish wax esters, with the exception of roe wax esters, which have sizeable amounts of polyunsaturated ...
Most fatty alcohols in nature are found as waxes, which are esters of fatty acids and fatty alcohols. [1] They are produced by bacteria, plants and animals for purposes of buoyancy, as source of metabolic water and energy, biosonar lenses (marine mammals) and for thermal insulation in the form of waxes (in plants and insects). [3]
Plants secrete waxes into and on the surface of their cuticles as a way to control evaporation, wettability and hydration. [3] The epicuticular waxes of plants are mixtures of substituted long-chain aliphatic hydrocarbons, containing alkanes, alkyl esters, fatty acids, primary and secondary alcohols, diols, ketones and aldehydes.

The systematic name of this enzyme class is acyl-CoA:long-chain-alcohol O-acyltransferase. Other names in common use include wax synthase, and wax-ester synthase. In general, wax syntheses naturally accept acyl groups with carbon chain lengths of C16 or C18 and linear alcohols with carbon chain lengths ranging from C12 to C20. [1]
Sugarcane wax consists of the following ingredients: about 70% of alcohols of long-chain hydrocarbons having chain lengths of C 18 to C 32, wax acids having chain lengths of C 18 to C 32, ω-hydroxycarboxylic acids and aromatic carboxylic acids. Also fatty alcohols (wax alcohols) and diols are alcohol components.
Spermaceti is a liquid wax, composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides, [17] with oleic acid being the most common fatty acid. The proportion of wax esters in the spermaceti organ increases with the age of the whale: 38-51% in calves, 58-87% in adult females, and 71-94% in adult males.
The level of wax esters in the spermaceti organ increases with the age of the whale: 38–51% in calves, 58–87% in adult females, and 71–94% in adult males. [4] Spermaceti wax is extracted from sperm oil by crystallisation at 6 °C (43 °F), when treated by pressure and a chemical solution of caustic alkali. Spermaceti forms brilliant white ...
