- RCH(NH2)COOH + HCHO + KOH → RCH(NHCH2OH)COOK + H2O
An unknown sample is reacted with a known amount of base. The remaining base is titrated with acid to determine the amount of excess base. The difference (total base minus excess) is equal to the amount of amino acid present in the original sample.
