Abstract
BECAUSE the sulphur amino-acids are so often the limiting amino-acids of human diets1,2, a relatively quick and accurate method for their estimation is useful in the determination of the protein value of a diet or dietary component. Such a method, utilizing performic acid oxidation and ion-exchange chromatography on a short (40-cm) resin column, is described here.
