Abstract:
The neutral maltase-glucoamylase complex has been purified to homogeneity from the brush-border membrane of rabbit intestine and kidney. Chemical modification of the amino acid side chains was carried out on the purified enzymes. Studies on the kidney enzyme revealed that tryptophan, histidine and cysteine were essential for both maltase and glucoamylase activities, whereas tryptophan, histidine and lysine were essential for the maltase and glucoamylase activities of the intestinal enzyme. Though there was no difference in the amino acids essential for the hydrolysis of maltose and starch by a

Abstract:
The present study investigated the effects of weaning modes on the intestinal pH, digestive enzyme activities, and intestinal morphology of piglets. A total of 27 litters of “Duroc boars × Landrace × Large White” piglets were selected and randomly divided into three groups. Those groups were the conventional weaning group (C), the odorant spray group (S), and the weaning-after-mixing group (M), with three repeats in each group and three litters in each repeat. The experiment began seven days before weaning, and ended seven days after weaning. The piglets were euthanized on the eighth day after

The activities of nine peptide hydrolases and three non-peptidase brush-border marker enzymes have been quantified in crude homogenates prepared from the proximal, mid and distal regions of small-intestinal mucosa for sham-operated (n = 9) and uraemic (n = 14) rats. Abnormalities in enzyme activities were observed in all regions studied in the uraemic group, although no reduction in food intake occurred. 2. The proximal region of the small intestine from uraemic rats showed a general fall in enzyme activities associated with the brush-border. This fall was combined with a decline in mucosal

Dietary effects of two diets high in protein from two marine species (Haliotis tuberculata and Anemonia viridis) as compared to a high-quality patron protein such as casein (or casein supplemented with olive oil) on intestinal and hepatic enzymes were studied. After 23 days, the two marine species as diet compared to casein increased the disaccharidase and alkaline phosphatase activities. Feeding Haliotis tuberculata meal produced a decrease on intestinal leucine aminopeptidase activity. The hepatic gamma-glutamyltranspeptidase activity decreased slightly in animals fed Haliotis tuberculata me

Abstract:
The gross intestinal configuration of the Nile tilapia intestine changed dramatically from a short, straight intestinal tube at hatch (day 0) to a very complex, coiling pattern first attained at 9 weeks post-hatch. During the developmental period, gut length increased from 90% to 410% of body length. The rate of increase in both intestinal and body lengths took place at an accelerating rate as the fish aged. The great intestinal length provides an advantage to the fish in digestion and absorption of nutrients present in the less energy-efficient herbivorous diet. Formulation of commercial diet
