What Is Citric Acid?

Citric acid (IUPAC: 3-carboxy-3-hydroxypentanedioic acid) is a naturally occurring organic tricarboxylic acid found mainly in citrus fruits such as lemons, oranges, and tangerines. Its chemical formula is C₆H₈O₇.

It is widely used as a natural preservative, antioxidant, acidity regulator, and chelating agent. In biochemistry, citric acid is a key intermediate in the citric acid (Krebs) cycle, which is essential for energy production in living organisms.
