Malic acid has two stereoisomers, a left-handed l-form and a right-handed d-form (Figure 6). Only l-malic acid occurs naturally in biological systems, whereas racemic mixture of d- and l-malic acid is produced synthetically.
D-(+)-Malic acid ((R)-Malic acid) is a dicarboxylic acid that is made by all living organisms. Malic acid has two stereoisomeric forms (L- and D-enantiomers). The malate anion is an intermediate in the citric acid cycle.
The dissociation constants for HCOOH and CH3COOH are 2.1104 and 1.8105 respectively.
There are also two different types of malic acid. L-Malic acid is only found in nature, while LD-Malic acid is produced synthetically. L-malic acid is not nearly as common as LD-Malic acid.
How is the acid dissociation constant (Ka) calculated? The acid dissociation constant (Ka) is calculated using the equation Ka = [H+][A-]/[HA], where [H+] is the concentration of hydrogen ions, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the acid.
