The activity level of digestive enzymes, especially carbohydrases, in various fish species is to a great extent dependent on the type of feeding and food composition. The most significant interspecies differences have been found for α-amylase, reali

Advances in the study of membrane digestion are described which relate to techniques for the separation of the apical glycocalyx and the study of the distribution of enzymes between the latter and the cell membrane. The regulatory properties of brush

1. 1. The absence of the effect of anoxia on the hydrolysis rate of a number of dipeptides and one tripeptide by the intact and homogenized mucosa of the small intestine in different mammals (rat, mouse and guinea pig) has been demonstrated. 2. 2. It

It is shown that certain key enzymes in membranous digestion (alkaline phosphatase, peptidase, gamma-amylase) are allosteric and ensure the autoregulation and the homoeostasis of the final stages of hydrolysis and of the initial stages of nutrient tr

Publisher Summary The small intestine performs two vital functions: (1) digestive-transport and (2) barrier-defensive. This chapter discusses the three-compartmental enzyme system of the enterocyte relating to its digestive and barrier functions. The

1. The hydrolysis of glycyl-L-leucine, glycyl-L-tyrosine, tributyrin, sucrose, maltose, soluble starch and α- and β-glycerophosphates by everted segments of rat intestine was estimated separately or in combination.2. A comparative study showed sign

We have confirmed Ugolev 's hypothesis that starch hydrolysis in the gut is not merely an intraluminal process but the most important hydrolytic activity occurs on the mucosa itself. Pancreatic amylase (α-1,4 glucan 4-glucanohydrolase, EC 3.2.1.1) w

As has been shown, the hydrolysis of disaccharides is accomplished by enzymes associated with certain structures of the intestinal epithelium cells. A more exact localization of the action of disaccharidases in the intestinal epithelium cells leads t

THE classical conception of digestion as being the sum of processes occurring in the chyme under the influence of hydrolytic enzymes fails to explain many important physiological and clinical phenomena.
