Radiolabeled linear and cyclic maltodextrins of high specific radioactivity were prepared using enzymes involved in maltodextrin metabolism. 14C-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 14C-labeled maltodexrins (< maltooctaose) using amylomaltase from Escherischia coli; ii) Cyclisation to alpha-cyclodextrin using cyclodextrin-glucosyltransferase of… Expand
