RCOOH represents a carboxylic acid, a type of organic compound characterized by the presence of a carboxyl group (-COOH). This functional group consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-OH). Carboxylic acids are known for their acidic properties and are commonly found in various natural substances, such as vinegar (acetic acid) and citric acid in citrus fruits. These compounds play significant roles in both biological and industrial processes. In biology, carboxylic acids are involved in metabolic pathways, such as the Krebs cycle, which is essential for energy production in cells. In industry, they are used in the production of plastics, food additives, and pharmaceuticals, highlighting their versatility and importance in everyday life.
