Organic acids are a diverse group of compounds that play important roles in various chemical and biological processes. Some common synonyms for organic acids include carboxylic acids, which are characterized by the presence of a carboxyl group (-COOH), as well as fatty acids, acetic acid, citric acid, malic acid, and oxalic acid. Organic acids are typically found in a wide range of natural sources, including fruits, vegetables, and dairy products. They are often used in food production as preservatives, flavorings, and acidifiers. Additionally, organic acids can also be used in industrial applications, such as the production of plastics and pharmaceuticals.
