| Citation | Distinguished for his studies of the soluble nitrogenous compounds of plants. He developed techniques for the quantitative recovery of amino acids separated by paper chromatography, and was led to the discovery that there were, in plants, many soluble nitrogenous compounds which were not constituents of proteins as well. He proceeded to isolate from ground nuts gamma methylene glutamine, gamma methylene glutamic acid and gamma methylene butyric acid. Subsequently he isolated from Tulipa, azetidine carboxylic acid, an analogue of proline, and from Cucurbits, N-ethyl-L-asparagine and beta-pyrazolylalanine. The structures of these hitherto unknown plant constituents were proved by synthesis. He has added to this signal achievement studies of the distribution and mechanism of biosynthesis of the new compounds, investigations which are being actively continued. His work has opened up a new field of research into the nitrogen metabolilsm of plants and his thorough knowledge of organic chemistry has enabled him to make a notable contribution to Botany and Biochemistry.
