Can enzymes pass through your large and or small intestines to enter your blood stream??
The enzymes I am most interested in are serratia, papain, bromelain, amylase, lipase.
If they do would they dissolve/eat "plaque" and other stuff that is not alive??

What exactly are you trying to accomplish w/the enzymes? I use them as a digestive aid to break down the carbs, protein and sugars in the food that is eaten. Are you talking about plaque in your arteries from high fatty foods? Enzymes will not dissolve the plaque only a diet that is healthy will accomplish that over a period. Let me know what your trying to accomplish.
