Citric Acid
Citric Acid is a weak organic acid. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle, and therefore occurs in the metabolism of virtually all living things.
Source:
Lemons, oranges, limes, and other citrus fruits possess high concentrations of citric acid.

Biochemistry:
Citric acid cycle -
Citrate, the conjugate base of citric acid is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.
The series of reactions is known by various names, including the "citric acid cycle", the "Krebs cycle" — Krebs cycle", and the "tricarboxylic acid (TCA) cycle".
Citrate is a critical component of bone, helping to regulate the size of calcium crystals.
Citrate is an inhibitor of phosphofructokinase, which helps regulate the rate of glycolysis (and subsequently the citric acid cycle) in the cell.
Role:
- It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. It is used mainly as an acidifier, as a flavoring, and as a chelating agent.
- At room temperature, citric acid is a white crystalline powder. It can exist either in an anhydrous (water-free) form or as a monohydrate.
- Citric acid is also used to remove fatty acids in blood vessels and to lower blood pressure.
