What are waxes in biology?
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. Whales and many fishes also store large quantities of waxes. …
What is wax made of?
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.
Are waxes solid or liquid?
Wax is a solid. When wax is below its melting temperature, it keeps its shape like other familiar solids such as concrete, wood, and iron, but when you light a wax candle, the heat from the flame melts the wax and turns it into a liquid.
Why are waxes hydrophobic?
Waxes. Waxes are similar to fats except that waxes are composed of only one long-chain fatty acid bonded to a long-chain alcohol group attached. Because of their long, nonpolar carbon chains, waxes are extremely hydrophobic (meaning they lack an affinity for water).
What is the function of wax?
Because of their hydrophobic nature, waxes prevent water from sticking on plants and animals. Synthetic waxes are derived from petroleum or polyethylene and consist of long-chain hydrocarbons that lack functional groups. Synthetic and waxes are used in adhesives, cosmetics, food, and many other commercial products.
What are the types of waxes?
There are two different types: soft wax and hard wax. Although both do a good job of removing hair from the follicle, hard wax is better for smaller, more sensitive areas like your bikini line. Soft wax, on the other hand, is a better option for larger areas like your legs.

What is the role of wax to an organism?
The roles of waxes in living organisms include; act as water repellents on leaves of some plants, serve as energy storage substances in microscopic aquatic plants and animals and the waxes also control rates of evaporation and hydration in plant.
What are three functions of waxes?
Waxes are used to make wax paper, impregnating and coating paper and card to waterproof it or make it resistant to staining, or to modify its surface properties.
