Malic acid is an organic compound with the molecular formula C4H6O5. It is a dicarboxylic acid that is made by all living organisms, contributes to the pleasantly sour taste of fruits, and is used as a food additive. Malic Acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists naturally. The salts and esters of Malic Acid are known as malates. The malate anion is an intermediate in the citric acid cycle.

Medical field
a. Because of its special position in metabolism circulation, Malic Acid can directly participate in human metabolism and be absorbed by the human body. It can provide energy to the body in a short time to eliminate fatigue；
b. Adding Malic Acid to drugs can increase drug stability and promote drug absorption. (for example, the amino acid fluid infusion, the Malic Acid improves the utilization of amino acids, and regulates the PH)；
c. L-Malic Acid as one of the basic components of drugs to treat heart disease, it is used to supplement k+ and mg2+ to maintain energy metabolism of myocardium.
