Abstract: Formation of the corresponding 2-ketoses and dehydration products of D-erythrose, D-threose, 5-deoxy-L-ribose, 5-deoxy-L-arabinose, and DL-glyceraldehyde on epimerization catalyzed by molybdate ions was examined by polarography. Transformation of D-erythrose and D-threose was accompanied, in addition to their mutual epimerization, also with formation of the corresponding 2-ketose and a product of dehydration. On the other hand, transformations of 5-deoxy-L-ribose and 5-deoxy-L-arabinose were associated with origination of the respective dehydration and epimerization products only. The course of transformations of aldoses under investigation was compared with the conversion of DL-glyceraldehyde.
