Adipic acid or hexanedioic acid is the organic compound with the formula (CH 2) 4 (COOH) 2. From an industrial perspective, it is the most important dicarboxylic acid : about 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon .
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
2-Oxoadipic acid, also known as α-ketoadipic acid, is an intermediate in the metabolism of lysine and tryptophan. [ 3 ] [ 4 ] The conjugate base and carboxylate is 2-oxoadipate or α-ketoadipate , which is the biochemically relevant form.
Alternately, it can be named as a "carboxy" or "carboxylic acid" substituent on another parent structure, such as 2-carboxyfuran. The carboxylate anion (R−COO − or R−CO − 2) of a carboxylic acid is usually named with the suffix -ate, in keeping with the general pattern of -ic acid and -ate for a conjugate acid and its conjugate base ...
The most widely used dicarboxylic acid in the industry is adipic acid, which is a precursor in the production of nylon. Other examples of dicarboxylic acids include aspartic acid and glutamic acid, two amino acids in the human body. The name can be abbreviated to diacid; long chain aliphatic dicarboxylic acids are known as fatty diacids.
Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined in water. In the original implementation, the resulting ammonium/carboxylate salt was isolated and then heated either in batches or continuously to induce polycondensation.
The final products after successive oxidations include succinic acid, which can enter the citric acid cycle, and adipic acid. The first step in ω-oxidation, i.e. addition of a hydroxy residue to the omega carbon of short, intermediate, and long chain unsaturated or saturated fatty acids, can serve to produce or inactivate signaling molecules.
For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger functional groups. A compound containing a ...
