L-(-)-Malic Acid Usage And Synthesis
Descriptionι-Malic acid is nearly odorless (sometimes a faint, acrid odor) with a tart, acidic taste. It is nonpungent. May be prepared by hydration of maleic acid; by fermentation from sugars.
Chemical PropertiesL-Malic acid is nearly odorless (sometimes a faint, acrid odor). This compound has a tart, acidic, nonpungent taste.
Chemical Propertiesclear colourless solution
OccurrenceOccurs in maple sap, apple, melon, papaya, beer, grape wine, cocoa, sake, kiwifruit and chicory root.
UsesThe naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective α-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid rece
UsesIntermediate in chemical synthesis. Chelating and buffering agent. Flavoring agent, flavor enhancer and acidulant in foods.
DefinitionChEBI: An optically active form of malic acid having (S)-configuration.
PreparationBy hydration of maleic acid; by fermentation from sugars.
Purification MethodsCrystallise S-malic acid (charcoal) from ethyl acetate/pet ether (b 55-56o), keeping the temperature below 65o. Or dissolve it by refluxing in fifteen parts of anhydrous diethyl ether, decant, concentrate to one-third volume and crystallise it at 0o, repeatedly to constant melting point. [Beilstein 3 IV 1123.]
