C6H8O7, commonly known as citric acid, is a weak organic acid found naturally in citrus fruits like lemons and oranges. It plays a crucial role in the Krebs cycle, a key metabolic pathway that generates energy in living organisms. Citric acid is widely used in food and beverage industries as a preservative and flavoring agent due to its sour taste. In addition to its culinary uses, citric acid is also employed in cleaning products and cosmetics for its chelating properties, which help to bind and remove metal ions. Its versatility makes it an important compound in various applications, from food preservation to industrial cleaning.
