Overview

A buffer component often used in the study and characterization of histidine proteins. Lactic acid on its own is a poor buffer at physiological pH, the imidizole ring provides buffering capabilities. L-β-Imidazolelactic acid has also been shown to provoke antioxidant effects at high concentrations (5-10 mM) in oxidative stress studies.
