Abstract
IN analysing tumour proteins, we1 have isolated without exception partially racemized glutamic acid. However, Chibnall and co-workers2 recently reported the isolation of optically pure l(+)-glutamic acid in four cases. These authors did not use the same method which we employed, but a different procedure which is excellent for the rapid and efficient isolation of natural glutamic acid from standard proteins.
