What is Syringic acid?
Description
Syringic acid is a naturally occurring O-methylated phenolic acid that can be enzymatically degraded by some bacteria as a source of methane or methanol. It is also a component of phenolic extracts from various plants that have antioxidant and prooxidant activities. Syringic acid has been shown to inhibit aldose reductase (IC50 = 213 μg/ml), proteasome activity, and cancer cell proliferation. Phenolic extracts containing syringic acid have been shown to inhibit α-amylase and α-glucosidase activities and reduce lipid peroxidation in vitro.
The Uses of Syringic acid
Syringic Acid is used in biological studies for electron transfer from plant phenolates to carotenoid radical cations with antioxidant interaction entering the Marcus theory inverted region.
