Citric acid is an organic tricarboxylic acid found in many biological systems and used widely in industry. Chemically, it is integral to cellular metabolism, notably serving as a key intermediate in the citric acid cycle, also known as the Krebs cycle. In this metabolic pathway, it facilitates the breakdown of acetyl-CoA derived from carbohydrates, fats, and proteins, leading to the generation of high-energy electron carriers that power cellular respiration. Beyond its biological role, the compound and its salts are utilized in the food industry as an acidity regulator and flavoring agent due to its tart taste, and it also has applications in industrial processes such as detergent formulation and the production of specialty chemicals.
