QUICK LINKS

DL-4-Hydroxyphenyllactic Acid is a racemic mixture of two enantiomers, D-4-Hydroxyphenyllactic Acid and L-4-Hydroxyphenyllactic Acid. L-4-Hydroxyphenyllactic Acid is a tyrosine metabolite. D-4-Hydroxyphenyllactic Acid is a metabolite that can be found in some bacteria. It likely comes from the breakdown of phenolic compounds in the microbe′s diet. The enzyme p-hydroxyphenylpyruvate oxidase metabolizes L-4-Hydroxyphenyllactic Acid. 4-Hydroxyphenyllactic acid, irrespective of its stereoisomeric form, may act to possess antioxidative properties. It decreases the production of reactive oxygen species (ROS) in both mitochondria and neutrophils, suggesting its potential role as a natural antioxidant. This characteristic may have implications for its protective effects against oxidative stress.
