A tricarboxylic acid is an organic carboxylic acid whose chemical structure contains three carboxyl functional groups (-COOH). The best-known example of a tricarboxylic acid is citric acid.
Tricarboxylic acid is used in the Citric Acid Cycle (TCA) which is fundamental to all aerobic lifeforms. This cycle converts NADH and FADH2 from pyruvate, which is created from citric acid.
