Biochem/physiol Actions

Malic acid is a dicarboxylic acid and an important regulatory metabolite. It has been implicated in process of fruit ripening. Malic acid is important for the starch metabolism; low malic acid content results in transient accumulation of starch. Mitochondrial-malate metabolism modulates ADP-glucose pyrophosphorylase activity and redox status of plastids.
