Fig. 5. Aminopeptidase-N activity of the anterior (A) and distal (D) portions of
the small intestine of fasted (following a 30-day fast, open bars) and fed (2
days postfeeding, solid bars) Python brongersmai, P. molurus, P. regius,
P. reticulatus and P. sebae. There were significant postprandial
increases in aminopeptidase-N activity of the anterior small intestine in all
species, and the distal small intestine in three species;
*P<0.05, **P<0.01,
***P<0.001.
