14C-Labelled methyl 2,6-di-O-pivaloyl-alpha-D-glucopyranoside was used as a substrate for the detection of esterase activity in the isolation of esterase II from rabbit serum. On treatment of methyl 2,6-di-O-pivaloyl-alpha-D-glucopyranoside with rabbit serum and esterase II, the 6-O-pivaloyl group was removed selectively. Likewise, the 6-O-pivaloyl group was removed selectively from methyl 2-acetamido-2-deoxy-3
