Pancreatic Lipase Activity in Deuterium Oxide.
Experimental Biology and Medicine, 1966 SummaryThe activity of purified pancreatic lipase, with tributyrin emulsified in gum arabic as the substrate, has been studied in ordinary water and in varying concentrations of D2O up to 100%. Estimates of maximum reaction velocities indicate that the degree of inhibition increases linearly with increasing D2O. At low substrate concentrations, however,
