Aspirin, the ester of salicylic acid, is prepared from acetic acid. Acetic acid is extensively used in the production of cellulose plastics and esters. For example, in addition to its use as a disinfectant, formic acid, the simplest carboxylic acid, is employed in textile treatment and as an acid reducing agent. Proteins are made up of amino acids, which also contain carboxyl groups.Ĭompounds in which the ―OH of the carboxyl group is replaced by certain other groups are called carboxylic acid derivatives, the most important of which are acyl halides, acid anhydrides, esters, and amides.Ĭlick Here to see full-size table Carboxylic acid derivatives have varied applications. Hydroxyl acids, such as lactic acid (found in sour-milk products) and citric acid (found in citrus fruits), and many keto acids are important metabolic products that exist in most living cells. The fatty acids are components of glycerides, which in turn are components of fat.
They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than the familiar mineral acids (e.g., hydrochloric acid, HCl, sulfuric acid, H 2SO 4, etc.).Ĭarboxylic acids occur widely in nature. The chief chemical characteristic of the carboxylic acids is their acidity. The carboxyl (COOH) group is so-named because of the carbonyl group (C=O) and hydr oxyl group. A fourth bond links the carbon atom to a hydrogen (H) atom or to some other univalent combining group.
