Crystalline trypsin
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. … WebThe formation of trypsin from trypsinogen by mold kinase is not accompanied by any measurable loss of protein. 6. The temperature coefficient of formation of trypsin from trypsinogen by mold kinase varies from Q 5–15 = 1.70 to Q 25–30 = 1.25 with a corresponding variation in the value of µ from 8100 to 4250.
