General description

Malic acid is used as a component of insect tissue culture. It is also useful as an acidulant in soft drinks, jams, fruit and vegetable juices.

Application

Malic acid has been used:
  • to induce basal respiration in mitochondrial cell culture
  • to measure the mitochondrial ETC (electron transport chain) activity
  • as a component of mitochondrial substrate stock

Biochem/physiol Actions

Malic acid is a part of cellular metabolism. Its application is recognized in pharmaceutics. It is useful in the treatment of hepatic malfunctioning, effective against hyper-ammonemia. It is used as a part of amino acid infusion. Malic acid also serves as a nanomedicine in the treatment of brain neurological disorders. A TCA (Krebs cycle) intermediate and partner in the malic acid aspartate shuttle.
