Conservation of Digestive Enzymes
Physiological Reviews, 2002The traditional understanding is that an entirely new complement of digestive enzymes is secreted by the pancreas into the small intestines with each meal. This is thought to be necessary because, like food itself, these enzymes are degraded during digestion. In this review we discuss experiments that bring this point of view into question.

Human Pancreatic Digestive Enzymes
Digestive Diseases and Sciences, 2007A primary function of the pancreas is to produce digestive enzymes that are delivered to the small intestine for the hydrolysis of complex nutrients. Much of our understanding of digestive enzymes comes from studies in animals. New technologies and the availability of the sequence of the human genome allow for a critical review of older reports and ...

Digestive enzymes of some earthworms
Experientia, 19804 species of tropical earthworms differed with regard to enzyme activity. The maximum activity of protease and of cellulase occurred in the posterior region of the gut of the earthworms. On the average Octochaetona surensis shows maximum activity and Drawida calebi shows minimum activity for all the enzymes studied.

Digestive tract enzymes in phoronida
Comparative Biochemistry and Physiology, 1969Abstract 1. 1. The digestive tract of Phoronis vancouverensis was examined histochemically for distribution of acid and alkaline phosphatases and esterase, and also by starch-gel electrophoresis. 2. 2. Phosphatases and esterases are found to be restricted to the oesophagus, preventriculus and stomach. 3. 3.

AbstractThe nature of endogenous enzymes in the alimentary tract of cattle is examined and their functions in digestive processes discussed. The main digestive enzymes in cattle are salivary and pancreatic lipase, rennin, pepsin, trypsin, lactase and amylase. Maltase and isomaltase, celliobiase, trehalase, elastase and carboxypeptidase are also present.

Enteropancreatic Circulation of Digestive Enzymes
Science, 1975Intact digestive enzymes can be absorbed by the intestine and resecreted by the pancreas. The pancreas, therefore, appears to be able to recycle proteins much as the liver recycles bile salts, although the magnitude of this process remains uncertain.
