Abstract
ACCORDING to the present conception the keto-acids occupy a central position in the synthesis of amino-acids. Attention has been paid especially to the ‘fundamental keto-acids’, namely, oxaloacetic acid and keto-glutaric acid, since the amino group of aspartic and glutamic acids formed from them is transferred to other keto acids. In green plants, however, keto-acids other than oxaloacetic acid—the presence of which in the growing legumes has recently been demonstrated in this laboratory1—have hitherto not been found, evidently due to the absence of suitable methods.
