Aminoacetaldehyde
Aminoacetaldehyde is the organic compound with the formula OHCCH2NH2. Under the usual laboratory conditions, it is unstable, tending instead to undergo self-condensation. Aminoacetaldehyde diethylacetal is a stable surrogate. In nature, aminoacetaldehyde is produced by oxygenation of taurine catalyzed by taurine dioxygenase, which produces the sulfite H2NCH2CH(OH)SO3−. See also * Aminoaldehydes and aminoketones Aminoaldehydes and aminoketones are organic compounds that contain an amine functional group as well as either a aldehyde or ketone functional group. These compounds are important in biology and in chemical synthesis. Because of their bifunctional ... References Amines Aldehydes {{amine-stub ...

Taurine Dioxygenase
In enzymology, a taurine dioxygenase () is an enzyme that catalysis, catalyzes the chemical reaction. :taurine + 2-oxoglutarate + O2 \rightleftharpoons sulfite + aminoacetaldehyde + succinate + CO2 The 3 substrate (biochemistry), substrates of this enzyme are taurine, 2-oxoglutarate, and oxygen, O2, whereas its 4 product (chemistry), products are sulfite, aminoacetaldehyde, succinate, and carbon dioxide, CO2. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The List of enzymes, systematic name of this enzyme class is taurine, 2-oxoglutarate:O2 oxidoreductase (sulfite-forming). Other names in common use include 2-aminoethanesulfonate dioxygenase, and alpha-ketoglutarate-dependent taurine dioxygenase. This enzyme participates in tau ...

Aminoaldehydes And Aminoketones
Aminoaldehydes and aminoketones are organic compounds that contain an amine functional group as well as either a aldehyde or ketone functional group. These compounds are important in biology and in chemical synthesis. Because of their bifunctional nature, they have attracted much attention from chemists. Tertiary amine derivatives Because primary and secondary amines react with aldehydes and ketones, the most common variety of these aminocarbonyl compounds feature tertiary amines. Such compounds are produced by amination of α-haloketones and α- haloaldehydes. Examples include cathinones, methadone, molindone, pimeclone, ferruginine, and tropinone. Secondary amine derivatives Aminoketones containing secondary amines are typically stable when the ketone is located on a ring, e.g. 4-piperidinone, triacetonamine, acridone Primary amine derivatives Most members of this class are unstable towards self-condensation, however some important examples do exist as intermediates in bi ...

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Self-condensation
Self-condensation is an organic reaction in which a chemical compound containing a carbonyl group acts both as the electrophile and the nucleophile in an aldol condensation. It is also called a symmetrical aldol condensation as opposed to a mixed aldol condensation in which the electrophile and nucleophile are different species. For example, two molecules of acetone condense to a single compound mesityl oxide in the presence of an ion-exchange resin: :2 CH3COCH3 → (CH3)2C=CH(CO)CH3 + H2O For synthetic uses, this is generally an undesirable, but spontaneous and favored side-reaction of mixed aldol condensation, and special precautions are needed to prevent it. Preventing self-condensation In many cases, self-condensation is an unwanted side-reaction. Therefore, chemists have adopted many ways to prevent this from occurring when performing a crossed aldol reaction. The use of a more reactive electrophile, and a non-enolizable partner If acetophenone and benzaldehyde are put toge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taurine
Taurine (), or 2-aminoethanesulfonic acid, is an organic compound that is widely distributed in animal tissues. It is a major constituent of bile and can be found in the large intestine, and accounts for up to 0.1% of total human body weight. It is named after Latin (cognate to Ancient Greek ταῦρος, ''taûros'') meaning bull or ox, as it was first isolated from ox bile in 1827 by German scientists Friedrich Tiedemann and Leopold Gmelin. It was discovered in human bile in 1846 by Edmund Ronalds. It has many biological roles, such as conjugation of bile acids, antioxidation, osmoregulation, membrane stabilization, and modulation of calcium signaling. It is essential for cardiovascular function, and development and function of skeletal muscle, the retina, and the central nervous system. It is an unusual example of a naturally occurring sulfonic acid. Chemical and biochemical features Taurine exists as a zwitterion , as verified by X-ray crystallography. The sulfonic aci ...

Amines
In chemistry, amines (, ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines). Important amines include amino acids, biogenic amines, trimethylamine, and aniline; Inorganic derivatives of ammonia are also called amines, such as monochloramine (). The substituent is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure , are called amides and have different chemical properties from amines. Classification of amines Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic ...
