Application

Phenylglyoxal hydrate was used :
  • to modify pig muscle carbonic anhydraseIII
  • as specific reagent for arginine groups
  • to prepare pyrrolinone and furan derivatives
  • as chemiluminescent reagent for the determination of purines

Biochem/physiol Actions

Phenylglyoxal is a potent inhibitor of mitochondrial aldehyde dehydrogenase. It reacts with arginine residues in purified Hageman factor (HF, Factor XII) and causes inhibition of its coagulant properties.
