D(+)-Malic acid Chemical Properties,Usage,Production
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:
- As a starting material for the enantioselective total synthesis of (?)-erinapyrone B.
- As a chiral organocatalyst in the synthesis of α-aminophosphonates from various aldehydes, aniline, and diethyl phosphite.
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.
