Distribution of digestive enzymes in gastrointestinal tract of young rhesus monkeys.
The distribution of different mucosal digestive enzymes along the gastrointestinal tract of young rhesus monkeys were studied by biochemical analysis of homogenized specimen from 13 different segments (i.e. stomach-fundus, body, antrum; small intestine-D1, D2, proximal, middle, distal; caecum; colon-ascending, transverse, descending and rectum), obtained from 6 monkeys of approximate age 8-12 months. The activity of all the enzymes was lowest in gastric mucosa rising through duodenum to peak in small intestine and declining towards the large bowel. There was no significant difference in levels of any of the enzymes between different parts of stomach or large bowel. This study suggests that like humans in rhesus monkeys maximum activity of digestive enzymes is present in small intestine and much less in gastric and large bowel mucosa.
