WebLanthionine ketenamine is a metabolite found in the mammalian brain and central nervous system.8 Due to imine-enamine tautomerism, it is often described as either a ketimine or a ketenamine. Its biosynthetic pathway involves transamination of the nonproteinogenic amino acid lanthionine, followed by cyclic imine formation (Scheme 1a).9 Web( 4) Lanthionine ketimine (LK ): 6 mmol (0.95 g) of L-cysteine is dissolved in 5 mL of water, and 6 mmol (1 g) of bromopyruvic acid in 2 mL of water is added. The condensation between brompyruvic acid and cysteine is followed-up by checking the disappearance of thiol group with the nitroprusside test.
