TI - The Determination of Amino-acids with Ninhydrin N2 - The colorimetric method for the determination of amino-acids based on the reaction with ninhydrin has been systeniatically examined. It has been found possible to obtain a stoicheiometric reaction for most amino-acids with a quantitative yield of diketohydrindylidenediketohydrindamine, the probable end-product of the reaction, by a simple procedure suitable for routine analysis UR - https://drive.google.com/file/d/19jR6oWIZWfceCHIcg2nkmp45tcUuRzsD/view?usp=drivesdk ER -
