Abstract

Abstract: The charge-transfer complexes of chloranil with five amino acids,Glycine,L-leucine,L-lysine,L-serine and L-cystine,were studied in detail by spectrophotometry.Anew and single method for the determination of amino acids has been established.The determinations was carried out in the solution of 20%(V%)ethanol with pH 9 at 350 nm.The equilibrium constants were determined.The composition of the charge-transfer complexes was also discussed.

Key words: Amino acids, Chloranil, Charge-transfer complexes
