I'm conducting an experiment using different concentrations of milk protein (powder) and a constant concentration of enzyme to compare reaction rates (which concentration of milk protein will turn translucent the fastest using a colorimeter).

I can either use pepsin or trypsin. Which enzyme is likely to react faster, providing the correct conditions?

Thanks
PLEASE note which sites or reference you're using as I'm going to write up a report. Thank you!

Pepsin is an enzyme from the stomach and so it will have a pH optimum in the range of 1-2. Milk protein precipitates if the pH is below 4 or so. So, I think using pepsin might be more difficult than using trypsin.

So, I'd suggest trypsin.

Don't get the question, what protein test are you referring to?
