WebApr 1, 1980 · The trypsin inhibitor activity of processed foods can be determined by measuring the loss of activity of added trypsin under standard conditions. Observed values are not usually independent of the degree of inhibition, and averaging over a range of inhibition levels or extrapolation to zero inhibition may not produce a more reliable value. … WebA Robust, Air-Stable, Reusable Ruthenium Catalyst for Dehydrogenation of Ammonia Borane; Electromagnetic Response Tensors for Normal Conducting Materials
