Trypsin inhibitor

Trypsin inhibitors are chemicals that reduce the availability of trypsin, an enzyme essential to nutrition of many animals, including humans.

There are four commercial sources of trypsin inhibitors.

A study revealing that proteinase inhibitor from the eggs of the freshwater snail Pomacea canaliculata, interacts as a trypsin inhibitor with the protease of potential predators, was reported in 2010, the first direct evidence for this mechanism in the animal kingdom.
