Enzymatic preparation of radiolabeled linear maltodextrins and cyclodextrins of high specific activity from [C-14] maltose using amylomaltase, cyclodextrin glucosyltransferase and cyclodextrinase

摘要

Radiolabeled linear and cyclic maltodextrins of high specific radioactivity were prepared using enzymes involved in maltodextrin metabolism. C-14-Labeled maltose was the starting material yielding products of identical specific radioactivity with respect to glucosyl residues. The enzymatic steps involved: i) Formation of linear C-14-labeled maltodexrins (
