Carboxylic acid Carboxylic acid A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH). The general formula of a carboxylic acid is R–COOH, with R referring to the rest of the (possibly quite large) molecule. Carboxylic acids occur widely and include the amino acids (which make up proteins) and acetic acid (which is part of vinegar and occurs in metabolism). Salts and esters of carboxylic acids are called carboxylates. When a carboxyl group is deprotonated, its conjugate base forms a carboxylate anion. Carboxylate ions are resonance-stabilized, and this increased stability makes carboxylic acids more acidic than alcohols, along with
Oxaloacetic acid given importance to oxaloacetate as without it, no aspartate would be formed and the following other amino acids would neither be produced. Oxaloacetate produces oxalate by hydrolysis. This process is catalyzed by the enzyme oxaloacetase. Oxaloacetic acid Oxaloacetic acid (also known as oxalacetic acid) is a crystalline organic compound with the chemical formula HOCC(O)CHCOH. Oxaloacetic acid, in the form of its conjugate base oxaloacetate, is a metabolic intermediate in many processes that occur in animals. It takes part in gluconeogenesis, the urea cycle, the glyoxylate cycle, amino acid synthesis, fatty acid synthesis and the citric acid cycle. Oxaloacetic acid undergoes
