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.

The protein corona (PC), which defines the biological identity of nanoparticles in the blood, is well-known, but no comprehensive and systematic study has been conducted yet on the formation of PCs in the gastrointestinal environment.

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.

Three test diets containing three different levels (1, 3, and 5 g kg−1) of dietary chitosan oligosaccharides (COs) were formulated and used to test the growth performance, body composition, intestine digestive enzymes, antioxidant responses and ...

Journal of the Science of Food and Agriculture, 1981
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.

Recruited lysosomal enzymes as major digestive enzymes in insects.
Biochemical Society Transactions, 2019The mass recruitment to the midgut contents of lysosomal proteolytic enzymes occurred in insects under three major selective pressures. Hemipteran (true bugs, aphids, and cicadas) ancestors lost their serine peptidases (SP) on adapting to feed on protein-

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.
