The name applied to the type of chemical (salts or organic acids and alcohols) which is formed when acids such as the hormone weedkiller acids are made to react with alcohols.
Term used to describe the "fruity" aromatics and flavors of beer. Apple, pear, grapefruit, strawberry, raspberry, and banana esters are often produced during the respiration cycle of yeast.
An organic salt; an acid neutralized with an alcohol.
carbonyl containing compound - see here for picture.
compound produced by the reaction between an acid and alcohol
any of a class of organic compounds corresponding to the inorganic salts and formed from an organic acid and an alcohol, usually with the elimination of water
a derivative of a carboxylic acid in which the −OH of the carboxyl group has been replaced by an −OR from an alcohol; the general formula is RCOOR.
Molecule formed by the condensation reaction of an alcohol group with an acidic group. Most phosphate groups are esters.
Any of a class of organic compounds made from the chemical reaction between an alcohol and an organic acid.
organic compound formed by combining an acid and an alcohol.
A compound formed by removal of water from an acid and an alcohol.
Term used to describe a fruity aroma of beer. Often an addition in a beer journal. Described with a fruit (i.e. an apple ester)
See carboxylic acid ester.
The substance arising by combination, with loss of water, of the carboxyl group of an organic acid with the hydroxyl group of an alcohol, with formation of an ester bond, -O-CO-. ~ See Also: Carboxyl group, Hydroxyl group, Thioester.
a chain composed primarily of carbon and hydrogen atoms
a chemical compound that is formed by the reaction of an organic or inorganic acid with an alcohol or with another organic compound containing the hydroxyl (-OH) radical
a chemical substance derived from an acid and an alcohol
a combination of an alcohol with an acid, the combination being associated with the elimination of water
a compound formed by elimination of water and bonding of an alcohol and an organic acid
a compound formed from an alcohol and an acid with the elimination of water, and are common among cosmetic ingredients
a compound made up of hydrogen and carbon atoms
a compound several generations removed from the original form
a molecule of a fatty acid and a fatty alcohol
an organic compound formed from an organic acid and an alcohol
A group of solvents made by reacting an acid with an alcohol, e.g., ethyl acetate, isopropyl acetate, "acetate" solvents.
Chemical combination of an alcohol and an organic acid. Fats are esters of glycerol and three fatty acids.
Flavor compounds naturally created during fermentation that add fruity, flowery and/or spicy flavors to beer.
a classification of organic compounds occurring naturally as oils and fats, produced by replacing the hydrogen of an acid by an alkyl, aryl, radical. A compound of an organic acid bonded via an ester bond to an alcohol. Any of a large group of organic compounds formed when an acid and alcohol is mixed. CH COOCH (Methyl acetate) is the simplest ester. Biodiesel is often described as a Fatty Acid Methyl Ester (FAME).
An organic compound formed by reacting an acid with an alcohol, always resulting in the elimination of water.
A volatile fruity odoured product of the reaction between a carboxylic acid and an alcohol.
an organic compound produced by the reaction between a carboxylic acid and an alcohol.
Any of a class of organic compounds corresponding to the inorganic salts formed from an acid by the replacement of hydrogen by an alkyl radical.
Esters are usually encountered as sweet smelling organic compounds commonly produced by many plants and fruits. However, the most common esters found in nature are fats and vegetable oils, which are esters of glycerol and fatty acids.
In chemistry, an organic compound in which an oxygen is bonded to carbon atom(s). In practical terms relevant to our discussion of androgens, esters of drugs are more soluble in oil (important for many injectable drugs) and longer-acting because it appears that the body must remove the ester chain before the compound can act at androgen receptors.
A group of solvents made by reacting an acid with an alcohol, eg. Ethyl acetate, isopropyl acetate etc.
Compounds formed by the reaction of an acid or an alcohol. The esters used in cosmetics are usually emollients and mostly designed to spread easily and penetrate into the contours of the skin more readily. They tend to resist rancidity better than natural oils and are designed to be used in place of these in products.
Formed by the combination of an alcohol with an organic acid; fats and oils are examples of esters.
An organic compound comparable to an inorganic salt. Formed by the reaction of an inorganic acid with an alcohol. Many forms are used for lubrication including phosphate esters, diesters and polyol esters. Only phosphate esters are approved by turbine OEM's for control systems.
Volatile flavor compound naturally created in fermentation. Often fruity, flowery or spicy.
An aromatic compound produced by yeast during fermentation. Contributes to the beer aroma spectrum.
The product of an organic acid and an alcohol.
chemical sometimes produced in the brewing process, producing a characteristic pear-drop aroma or flavour
The compound formed during the reaction between an alcohol and an acid.
an ester is a compound formed from the reaction between and acid and an alcohol. In esters of carboxylic acids, the –COOH group of the acid and the –OH group of the alcohol lose water and become a –COO- linkage.
Flavor compounds produced by the action of yeast turning sugars into alcohol and carbon dioxide. Esters may be fruity or spicy.
An organic compound formed by the reaction of an acid (organic or inorganic) with an alcohol.
Compounds formed by the reaction of alcohols and organic acids.
An organic compound, comparable to an inorganic salt, formed by the reaction of an acid and an alcohol, or phenol, with the elimination of water.
a compound formed by the reaction between an alcohol and an acid. Many esters are liquids. They are frequently used as plasticizers in rubber and plastic compounds.
A Compound of the general formula R-C-O-R1 where R and R1 may be the same or different, and may be either aliphatic or aromatic.
A compound formed by reaction of an acid and an alcohol accompanied by the loss of water formed during the reaction.
The chemical reaction product of an alcohol and an acid.
A compound formed by the reaction between an acid and an alcohol with the elimination of a molecule of water.
A general term for any organic molecule produced by combining an acid with an alcohol.
In chemistry, esters are organic compounds in which an organic group (symbolized by R' in this article) replaces a hydrogen atom (or more than one) in an oxygen acid. An oxygen acid is an acid whose molecule has an - group from which the hydrogen (H) can dissociate as an H+ ion.
