It should be noted that in single intragastric administration of the pesticide decis there was noted inhibition of the activity of invertase, dipeptidase and alkaline phosphatase in the proximal and distal parts of the intestine, particularly marked desactivation was revealed in the proximal part of the intestinal mucosa.
For characteristic of the enzymatic activity of the small intestine there was performed study of the activity of dipeptidase, amylase, invertase and alkaline phosphatase in the homogenate of the mucosal membrane from proximal and distal parts in multiple effects of pesticide decis in toxic dose (1/20 LD50 ) during 4 months.
For example, the reduced growth may indirectly give rise to increased turnover of GAPDH and the Xaa-His dipeptidase
Key words: Piperine, brush border membrane, fluidity, leucine amino peptidase, glycyl-glycine dipeptidase, kinetics, microvilli
Glycyl-glycine dipeptidase (GGDP): GGDP activity was determined by the decrease in absorbance at 220 nm due to the hydrolysis of peptide bonds (Josefson and Lindberg, 1965).
activity and intensity of absorbtion of amino acid in the intestine of chickens fed on diets containing enzyme preparation.
The presence of salseed meal tannins in the diets of fowl results in lowered digestibility of protein, reduced activities of digestive enzymes (trypsin, chymotrypsin, [beta]-amylase, dipeptidase
and disaccharidases) in the gut lumen and increase in the relative weight of the pancreas (Mahmood et al.
The quantities measured and the corresponding analyzers were as follows: serum concentrations of apolipoprotein A1, apolipoproteins B, bilirubin (nonesterified), chloride, cholinesterase, HDL-cholesterol, L-lactate dehydrogenase, lipoprotein(a), pancreatic a-amylase, peptidyl dipeptidase
A, transferrin, and triacylglycerol lipase were measured with the Modular System (Roche Diagnostics); serum magnesium concentrations were measured with the Dimension RxL (Dade Behring); serum concentrations of CA 15-3 antigen, CA 19-9 antigen, CA 125 antigen, a-fetoprotein, [[beta].
Sequence identification and characterization of human carnosinase and a closely related non-specific dipeptidase
It has been suggested that low iron absorption in these patients may be explained by the intestinal mucosal changes that develop with uremia, including changes in activity of certain digestive enzymes--decreased activity of dipeptidases
and increased activity of disaccharidases.
Os aminoacidos liberados pelas dipeptidases
citossolicas no meio intracelular dos enterocitos podem ser utilizados pela propria celula ou liberados para a circulacao portal, mediante transportadores de aminoacidos localizados na membrana basolateral.
9 mmol/L in whole blood, respectively (15)], followed by a degradation pathway via reactions catalyzed by [gamma]-glutamyltranspeptidase and dipeptidases
