BACKGROUND The purpose of this study was to clarify whether it is possible to extrapolate results from studies of the hydrolyzing activity of disaccharidases from rats to humans. MATERIALS AND METHODS We measured disaccharidase activity in humans and rats using identical preparation and assay methods, and investigated the similarity in hydrolyzing activity. Small intestinal samples without ma...

Vitamins are essential for the proper functioning of body, and Folic Acid, also known as Vitamin B9, has many benefits body. Acid contributes to normal development fetus, preventing risk fetal birth defects, mainly represented by neural tube defects orofacial clefts. At same time, deficiency can cause serious health problems. That is why it necessary know roles in symptoms deficiency, but what ...

Bacillus brevis NRRL B-4389 produced extracellular maltase (alpha-glucosidase; EC 3.2.1.20) only in the presence of short alpha-1,4-glucosidic polymers, such as maltose and maltotriose. An optimum medium was developed; it contained 2.5% maltose, 0.5% nonfat dry milk, 0.4% yeast extract, and 0.01% CaCl(2). The enzyme was produced extracellularly during the logarithmic phase of growth; no cell-bo...

The pH optimum of pancreatic cx-amylase from grain-fed steers was determined to be 6.9, while that of intestinal maltase was established at 5.8. Both assays were found to be linear up to 1 hr of incubation. The Vma x of pancreatic amylase was determined to be 1.15 mg of maltose monohydrate produced/hr. Activities of pancreatic and intestinal maltase were not reduced (P>.05) during the interval ...

The effects of dietary vitamin E levels on mucosal maltase and alkaline phosphatase (ALP) enzyme activities and on the amount of mucosal malonyldialdehyde (MDA) in broiler chickens were studied in the present study. One hundred and eighty of male day old broiler chicks (Ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. Chickens...

boron (b) is a non-metal micronutrient which is essential for plants growth and development. formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. it has been suggested that b-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...

background: the physiologic function of carnitine, oxidation of fatty acid and lipid  metabolism, is severely affected in carnitine deficiency, secondary forms of which lead to renal tubular disorders and chronic renal failure. reduction in serum carnitine has been frequently reported in patients and experimental animals treated with antiepileptic drugs, one of which, valproic acid has consiste...
