It is one of a series of compounds involved in the physiological oxidation (see oxidation-reduction)of fats, proteins, and carbohydrates to carbon dioxide and water. It has a characteristic sharply sour taste and is used in many foods, confections, and soft drinks. It is added to certain foods to improve their stability in metal containers. Industrially, it is used as a water conditioner, cleaning and polishing agent, and chemical intermediate .
