What are waxes in biochemistry?
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.
What is wax in biology?
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.
What is the function of a wax?
The main purpose of the waxes is presumed to be to give a water-proof layer to the feathers, but other functions have been suggested. Some of these lipids can also have a role as pheromones in sexual signalling.
What is a wax in nutrition?
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 ( CH3(CH2)15OH) and palmitic acid (CH3(CH2)14COOH).
What is wax made up of?
All waxes are primarily hydrocarbons, whether the wax is of animal, vegetable, or petroleum origin. The chemical composition of all waxes used for candle-making is similar, and all candle waxes burn in the same manner.
What is chemical formula of wax?
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal or oil shale that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms….Paraffin wax.

What is an example of a wax?
Wax is a sticky substance that is made from honeycomb or any substance with a similar feel. An example of wax is the substance produced by a burning candle. An example of wax is what you clean out of your ears with a cotton swab.
What are the properties of wax?
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. Waxes are insoluble in water but soluble in organic, nonpolar solvents.
How wax is produced?
Beeswax is the most common type of animal wax. Worker bees produce it in a hive, and honeybees use it to build honeycomb cells. The wax is harvested by melting an empty honeycomb in boiling water. Beeswax is used in many products, including candles and cosmetics.
What is the elements of wax?
A wax is a simple lipid which is an ester of a long-chain alcohol and a fatty acid. The alcohol may contain from 12-32 carbon atoms. Waxes are found in nature as coatings on leaves and stems. The wax prevents the plant from losing excessive amounts of water.

What is the source of wax?
Paraffin wax is obtained from petroleum by dewaxing light lubricating oil stocks. It is used in candles, wax paper, polishes, cosmetics, and electrical insulators.
