Biochem/physiol Actions

Sodium citrate can act as a buffering agent, resisting changes in pH. Used in blood collection tubes, the citrate chelates calcium ions in blood and thereby disrupts blood clotting. Citrate is a intermediate in the TCA cycle and fatty acid synthesis. Citrate is an allosteric modulator of acetyl-CoA carboxylase, the enzyme that regulates the conversion of acetyl-CoA to malonyl-CoA.
