| D(+)-Malic acid Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powde |
| 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 | D-(+)-Malic acid used as an acidulant and flavoring agent, food additive. And it is also used in the place of the less sour citric acid in sour sweets. |
| Uses | D-(+)-Malic acid can be used:
|
| Definition | ChEBI: An optically active form of malic acid having (R)-configuration. |
| Biological Activity | D-(+)-Malic acid, an active isomer of Malic acid, is a competitive inhibitor of L(--)malic acid transport. |
| Synthesis | Malic acid is isolated from immature apples; industrially prepared is obtained by catalytic oxidation of benzene, then reacting with water at high temperature and high pressure to generate maleic anhydride. |
| in vitro | Some bacteria belonging to Arthrobacter, Brevibacterium, Corynebacterium, Pseudomonas, Bacillus, and Acinetobacter produced D-(+)-Malic acid (D-Malic acid) from Maleic acid when the cells grown in a medium containing citraconic acid are reacted aerobically with Maleic acid in the pH 7.0 phosphate buffer containing 0.1% sodium chloride. |
