INSERTION OF OXIMIC AND HYDROXAMIC FUNCTIONS INTO ONE SIMPLE AMINO-ACID CREATES A NEW FAMILY OF POWERFUL CHELATING-AGENTS

2-(Hydroxyimino)propanohydroxamic acid, a derivative of alanine in whi ch the amino group has been transformed into oxime and the carboxylic group into a hydroxamic function, is a more powerful chelating agent f or Cu2+ and Ni2+ ions than alanine itself, its oximic or hydroxamic an alogues.
