Esters are chemical compounds A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds derived by reacting an oxoacid Under Lavoisier's original theory, all acids contained oxygen, which was named from the Greek οξυς (acid, sharp) and γεινομαι (geinomai) (engender). It was later discovered that some acids, notably hydrochloric acid, did not contain oxygen and so acids were divided into oxoacids and these new hydracids (one containing an oxo group, X=O) with a hydroxyl Hydroxyl in chemistry stands for a molecule consisting of an oxygen atom and a hydrogen atom connected by a covalent bond . The neutral form is a hydroxyl radical and the hydroxyl anion is called a hydroxide. When the oxygen atom is linked to a larger molecule the hydroxyl group is a functional group (OH) . Hydroxide (HO¯ or ¯OH anion) is a compound such as an alcohol In chemistry, an alcohol is any organic compound in which a hydroxyl group (-O or phenol Phenol, also known as carbolic acid, is a toxic, white crystalline solid. Its chemical formula is C6H5O .[1] Esters are usually derived from an inorganic acid A mineral acid is an acid derived from one or more inorganic compounds. A mineral acid does not contain any carbon atoms and all mineral acids release hydrogen ions when dissolved in water or organic acid An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids whose acidity is associated with their carboxyl group -COOH. Sulfonic acids, containing the group -SO2OH, are relatively stronger acids. The relative stability of the conjugate base of the acid determines its acidity. Other groups in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl In chemistry, an alkyl group is a hydrocarbon; typically an alkyl is a part of a larger molecule. The term is usually used loosely; there is no general formula for an alkyl group. In structural formulae, an alkyl group is represented with an R. Usually, alkyl groups resemble hydrocarbons, but with one less hydrogen atom. The smallest alkyl group (alkoxy In chemistry, the alkoxyl group is an alkyl group linked to oxygen thus: R-O. The range of alkoxy groups is as great, the simplest being methoxy (-OCH3). An ethoxy group (-OCH2CH3) is found in the organic compound phenetol, C6H5OCH2CH3 which is also known as ethoxy benzene. Related to alkoxy groups are aryloxy groups) group, and most commonly from carboxylic acids Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -COH, usually written -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids — they are proton donors. Salts and anions of carboxylic acids are called carboxylates and alcohols In chemistry, an alcohol is any organic compound in which a hydroxyl group (-O .
Esters are ubiquitous. Many naturally occurring fats and oils are the fatty acid In chemistry, especially biochemistry, a fatty acid is a carboxylic acid often with a long unbranched aliphatic tail , which is either saturated or unsaturated. Carboxylic acids as short as butyric acid (4 carbon atoms) are considered to be fatty acids, whereas fatty acids derived from natural fats and oils may be assumed to have at least eight esters of glycerol Glycerol is a chemical compound also commonly called glycerin or glycerine. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. For human consumption, glycerol is classified by the FDA among the sugar alcohols as a caloric macronutrient. Glycerol has three hydrophilic hydroxyl groups that are responsible. Esters with low molecular weight are commonly used as fragrances and found in essential oils An essential oil is a concentrated, hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile or ethereal oils, or simply as the "oil of" the plant from which they were extracted, such as oil of clove. An oil is "essential" in the sense that it carries a distinctive scent, or and pheromones A pheromone is a chemical signal that triggers a natural response in another member of the same species. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Their use among insects has been particularly well documented. In addition, some vertebrates and plants communicate by using. Phosphoesters A phosphodiester bond is a group of strong covalent bonds between the phosphorus atom in a phosphate group and two other molecules over two ester bonds. Phosphodiester bonds are central to all life on Earth, as they make up the backbone of the strands of DNA. In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one form the backbone of DNA Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed molecules. Nitrate esters, such as nitroglycerin Nitroglycerin , (United States spelling) also known as nitroglycerine, (UK Spelling), trinitroglycerin, trinitroglycerine, 1,2,3-trinitroxypropane and glyceryl trinitrate, is a heavy, colorless, oily, explosive liquid obtained by nitrating glycerol. Since the 1860s, it has been used as an active ingredient in the manufacture of explosives,, are known for their explosive properties, while polyesters Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate . Polyesters include naturally-occurring chemicals, such as in the cutin of plant cuticles, as well as are important plastics Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials suitable for the manufacture of industrial products. Plastics are typically polymers of high molecular weight, and may contain other substances to improve performance and/or reduce costs, with monomers linked by ester moieties.
