Ester An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group, as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; th...
An ester is an organiccompoundwhere thehydrogenin the compound'scarboxyl groupis replaced with ahydrocarbongroup. Esters are derived from carboxylic acids and (usually) alcohol. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester. The chemical formula ...
When a carboxylic acid reacts with an alcohol in the presence of concentrated sulfuric acid, an ester is formed. Concentrated sulfuric acid is a catalyst for this reaction.Below are links to the reactions of carboxylic acids and alcohols. Click on the name of the ester to see the reaction....

A substance called L-arginine ethyl ester (LAE) is an arginine amino acid derivative. It is made through a process called esterification, wherein a carboxylic acid and an alcohol combine to produce a compound called ethyl ester. Arginine is an important component of proteins but is called a ...
It can be used as benzyl-protecting group for carboxylic acid and alcohol hydroxy. Benzyl-protecting group can be removed by hydrogenation easily. In addition, benzyl alcohol can also be easily oxidized to benzoic acid by a variety of oxidants. If nitric acid is used, it can be oxidized to...
