Biological and Metabolic Role

Citrate, the anion of trisodium citrate, is a key intermediate in the citric acid cycle (TCA cycle), a core metabolic pathway for energy production in the body. It also plays a role in fatty acid synthesis and acts as a modulator for certain enzymes like acetyl-CoA carboxylase. The compound has a high safety profile; the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has not specified a limit for its acceptable daily intake (ADI).

Main Applications and Uses

The versatility of trisodium citrate comes from its properties as a buffering agent, chelating agent, and anticoagulant.
