摘要: 本文用分光光度法研究了5种氨基酸与四氯苯醌形成的荷移配合物.通过对影响配合物形成因素的研究,确立了以四氯苯醌形成荷移配合物的方法测定氨基酸的最佳反应条件,测定了反应平衡常数.讨论了配合物的组成.

关键词: 氨基酸, 四氯苯醌, 荷移配合物

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
