An ester is a organic functional group made up of a carbonyl and an alkoxy. Due to unshared electrons on oxygen, esters are comprised of two resonance structures which contribute to its stability Ester, any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common.

Ester Structure Esters are ubiquitous in nature and are involved in many key metabolic processes, examples of which include the storage of fatty acids as triglycerides (fatty acid esters of the polyalcohol glycerol) or the transport of cholesterol as their lipophilic cholesterol esters.

Structure of Ester. Esters feature a carbon-to-oxygen double bond that is also singly bonded to a second oxygen atom. The oxygen atom is further connected to an aryl or an alkyl group. They come in all shapes and sizes.

In chemistry, 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 group.

They come in all shapes and sizes. Esters are a functional group commonly encountered in organic chemistry. They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen. The singly bound oxygen is bound to another carbon. Ester names are derived from the parent alcohol and the parent acid.

Nicotinamide amides can exist in either a cis or trans geometry 7 kcal/mol Cis = ground state Trans = reduction Ethyl esters are chemical compounds belonging to the group of carboxylic acid esters. They are formed by the esterification of a carboxylic acid with ethanol. They have the characteristic functional ester group.

Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound would be a carboxylic acid.) Figure 15.4 "The Structure of Esters" shows models for two common esters.

Esters feature a carbon-to-oxygen double bond that is also singly bonded to a second oxygen atom, which is then joined to an alkyl or an aryl group. The esters shown here are ethyl acetate (a) and methyl butyrate (b). Esters occur widely in nature.

Esters are derived from carboxylic acids. A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring such as a phenyl or benzyl group. The most commonly discussed ester is ethyl ethanoate. In chemistry, 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 group. Usually, esters are derived from a substitution reaction of carboxylic acid and an alcohol . Ester Structure.
