| L-(-)-Malic Acid Usage And Synthesis |
| Description | ι-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 Properties | L-Malic acid is nearly odorless (sometimes a faint, acrid odor). This compound has a tart, acidic, nonpungent taste. |
| Chemical Properties | clear colourless solution |
| Occurrence | Occurs in maple sap, apple, melon, papaya, beer, grape wine, cocoa, sake, kiwifruit and chicory root. |
| Uses | The 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 |
| Uses | Intermediate in chemical synthesis. Chelating and buffering agent. Flavoring agent, flavor enhancer and acidulant in foods. |
| Definition | ChEBI: An optically active form of malic acid having (S)-configuration. |
| Preparation | By hydration of maleic acid; by fermentation from sugars. |
| Purification Methods | Crystallise S-malic acid (charcoal) from ethyl acetate/pet r (b 55-56o), keeping the temperature below 65o. Or dissolve it by refluxing in fifteen parts of anhydrous diethyl r, decant, concentrate to one-third volume and crystallise it at 0o, repeatedly to constant melting point. [Beilstein 3 IV 1123.] |
