Seeyour text for a review of digestive enzymes and their functions.

Because they are not actively transported, fructose and sugar alcohols are only absorbed down their concentration gradient, and after a moderately high intake, some may remain in the intestinal lumen, acting as a substrate for bacterial fermentation.
Disaccharides cannot be absorbed through the wall of the small intestine into the bloodstream, so in the absence of lactase, lactose present in ingested dairy products remains uncleaved and passes intact into the colon.

Pancreatic amylase, an isoenzyme of salivary amylase, differs only in the optimum pH of action.

If you haven't tried Pro JYM, then prepare to be blown away by the highest quality protein powder ever developed that includes all the critical ingredients you need, avoids any unnecessary and/or counterproductive ingredients, delivers unparalleled results, is the absolute best-tasting protein powder that you have ever tried, and leaves you with no stomach discomfort. In fact, even those who are lactose intolerant have zero stomach issues with Pro JYM. That's because each serving of Pro JYM has less than 1 gram of lactose to avoid such stomach issues.

These two are active only within our digestive system.

T1 - The role of protein synthesis and digestive enzymes in acinar cell injury

Several mechanisms have evolved to mitigate the dangers posed by inappropriate activation of digestive enzymes within the pancreas (). Animals engineered to express a mutant trypsinogen that becomes activated within the trans-Golgi network of the secretory pathway showed a transient loss of zymogen granules, which was followed by complete recovery of granule production despite continued expression of this mutant. This observation suggests that pancreatic acinar cells can upregulate protective mechanisms. However, as yet, these mechanisms have not been identified. Reasonable candidates include the upregulation of trypsin inhibitors such as pancreatic secretory trypsin, or an increase in trypsin-degrading enzymes, such as chymotrypsin-C. Trypsin-stimulated induction of apoptosis might be another potential coping mechanism; high levels of intracellular trypsin activity can cause acinar cells to undergo apoptosis., Apoptosis is a means of both eliminating unhealthy cells and limiting the inflammatory cascade.

between food enzymes and digestive enzymes is ..

The major protein-digesting enzymes in the digestive system are pepsin, trypsin, and chymotrypsin.
Pepsin is the most important of this group, and it is part of an enzyme group called aspartate proteases.

or it may be stored in the lysosome as a digestive enzyme

If you look on the Supplement Facts Panel and Ingredients List of Pro JYM, you will notice that I didn't bother to add any enzymes, specifically proteases that work to digest protein.

Protein; Protein Digestion Inside the Human Body

Some of you may be shocked to find that I failed to include protease enzymes in my high-quality Pro JYM protein-powder blend. After all, everyone knows how important enzymes are for digesting protein, right? Wrong! If you're surprised that my Pro JYM lacks digestive enzymes, then you will likely be even more surprised to hear that the science on digestive enzyme supplements is almost non-existent.

Another of the types of protein-digesting enzymes are called exopeptidases and are manufactured in the pancreas.
Another group of protein-digesting enzymes controls the circulation of proteins by degrading excess or damaged molecules.
