The rate of a reaction catalyzed by enzymes is influenced by various factors, including temperature, pH, chemical substances, etc.1 In this work, the influence of temperature on enzyme operational stability was studied. Temperature deactivation of an enzyme is usually defined as a transformation of an active enzyme into denaturated (deactivated) form, described by an irreversible first-order re...

Abstract Insulin concentrations are variable in bovine colostrum (5 to 263 µg insulin/L) and its effects on gastrointestinal function neonatal calves unknown. The objective of this study was determine if varying insulin would influence intestinal carbohydrases Holstein bulls. Calves (n = 26; 49.11 kg, SD 3.24) were removed from their dams after calving. They fed 3 meals (7% BW or 3.10 ± 0.02 L)...

The most economically important species used in a wide range of fermentation industries throughout Asia belong to Aspergillus section Flavi, which are morphologically and phylogenetically indistinguishable, with a few being toxigenic and therefore a major concern. They are frequently isolated from Korean fermentation starters, such as nuruk and meju. The growing popularity of traditional Korean...

The 100000g supernatants from 13-day-old suckling-rat intestinal homogenates contained 43.5% of the total intestinal maltase activity, compared with 7.1% in weaned adult rats aged 40 days. The soluble maltase activity was separated on Sepharose 4B into two quantitatively equal fractions at pH6.0, one containing a maltase with a neutral pH optimum and the other a maltase with an acid pH optimum....

The periodic rise and frequency of diabetes mellitus (DM) have pressured into the quest for other possible anti-diabetic remedies from medicinal plants. foremost strategies engaged in lessening gastrointestinal glucose levels by hindrance carbohydrate digesting enzyme prominently as α-glucosidase . Acarbose, currently used an inhibitor, is a useful treatment option management hyperglycemia type...

BACKGROUND Over a 10 year period a decline in the rate of sensitizations to α-amylase (Aspergillus oryzae) was observed in bakers investigated for allergic obstructive airway disease. At the same time, glucoamylase (Aspergillus niger) was identified as the currently the most relevant allergen in sensitizations to enzymes in the baking industry. The aim of the present study was to investigate wh...

The aim was to evaluate the activity of intestinal carbohydrases in patients with irritable bowel syndrome (IBS) symptoms food intolerance. Material and methods. 126 IBS (83 women 43 men, median age – 32.0 years (Q1–Q3: 27–38 years)) were examined. diagnosis established on basis Roman Criteria IV. A questionnaire conducted for all identify intolerances, according results which divided into thre...
