1. Ester

   In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which at least one acidic hydrogen atom (−H) of that acid is replaced by an organyl group (−R). An example of an ester formation is the substitution reaction of a carboxylic acid (RC(=O)−O−H) and an alcohol (R'OH), forming an ester (RC(=O)−O−R'), where R and R′ denote organyl groups, or H in the case of R. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. Esters can be formed from oxoacids (e.g. esters of acetic acid, carbonic acid, sulfuric acid, phosphoric acid, nitric acid, xanthic acid), but also from acids that do not contain oxygen (e.g. esters of thiocyanic acid, trithiocarbonic acid, tricyanomethane). Esters of organic oxoacids typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters of phosphoric acid form the backbone of DNA molecules. Esters of nitric acid, such as nitroglycerin, are known for their explosive properties.

1. ester

   An ester is an organic compound that is derived from an acid (most commonly a carboxylic acid) in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group. They are usually derived from a carboxylic acid and an alcohol. They are characterized by the presence of a carbonyl group (C=O) and an ether group (R-O-R'). The general formula for an ester is RCOOR', in which R and R' are any organic groups.

1. Esternoun

   an ethereal salt, or compound ether, consisting of an organic radical united with the residue of any oxygen acid, organic or inorganic; thus the natural fats are esters of glycerin and the fatty acids, oleic, etc

2. Etymology: [A word invented by L. Gmelin, a German chemist.]

1. Ester

   Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and alcohols. That is, esters are formed by condensing an acid with an alcohol. Esters are ubiquitous. Most naturally occurring fats and oils are the fatty acid esters of glycerol. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties.
