Waxes

Waxes are a type of organic compound that are long-chain fatty acids and long-chain alcohols. They are found in nature and have a wide range of uses and importance.

Structure

Waxes are composed of a fatty acid and a long-chain alcohol. The fatty acid component is usually a saturated or unsaturated carboxylic acid, while the alcohol component is a long-chain alcohol. This combination creates a molecule that is nonpolar and hydrophobic, making waxes water-repellent and useful for many applications.

Functions and Uses

Waxes have several important functions and uses in nature and in human society. In nature, waxes are used by plants and animals for protection against water loss, as a barrier against pathogens and predators, and for various other structural and protective roles. In human society, waxes are used in a wide range of products, including candles, cosmetics, polishes, pharmaceuticals, and food products.

Examples of Waxes

Some common examples of waxes include beeswax, which is produced by honeybees and used in candles and cosmetics, and carnauba wax, which is derived from the leaves of the carnauba palm and used in car waxes, shoe polishes, and food products.
