C6H5O7

C6H5O7 is the molecular formula for citrate, a form of citric acid. Citric acid is a weak organic acid found naturally in citrus fruits. In its ionized form, citrate plays a crucial role in cellular respiration, particularly in the Krebs cycle (also known as the citric acid cycle), where it is involved in the metabolic breakdown of carbohydrates, fats, and proteins to produce energy.

Citrate is also a vital component in various biological processes. It acts as a chelating agent, meaning it can bind to metal ions, which is important for preventing excessive metal accumulation in the body. In the blood, citrate is used as an anticoagulant by binding to calcium ions, which are essential for blood clotting.

Industrially, citric acid and its salts (citrates) are widely used as acidulants, flavor enhancers, and preservatives in the food and beverage industry. They are also found in pharmaceuticals, cosmetics, and cleaning products due to their chelating and pH-adjusting properties. The molecular formula C6H5O7 represents the citrate anion, which has lost one proton from the carboxylic acid groups of citric acid.
