activity including lactase, sucrase, and maltase were measured by glucose oxidase-peroxidase conjugated method according to Hou et al.
Commensal organisms may synthesize glycosidase, leading to damage of glycocalyx or disaccharidases
The specific activity of the disaccharidases
maltase and sucrase was determined using 56 mM maltose or sucrose as substrate in 100 mM sodium maleate, pH 6.
2011) and suppressing disaccharidase
activities (Liu et al.
Oral zinc supplements in non-responsive coeliac syndrome: effect on jejunal morphology, enterocyte production, and brush border disaccharidase
Distribution of disaccharidase
activity in the small bowel of normal and lactase-deficient subjects.
In some instances, decreased activity of digestive enzymes such as disaccharidases
may cause a secondary lactose intolerance and mal-absorption of nutrients.
Physiological constraint on feeding behavior: intestinal membrane disaccharidases
of the starling.
A lack of disaccharidases
can result in the inhibition of complete decomposition of carbohydrates, as well as in the absorption of monosaccharides conversion and utilization (Karamouz et al.
Also, Et0Ac and n-BuOH fractions inhibited in vitro disaccharidases
activities after an acute treatment.
The fact that HFCS consists mainly of two monosaccharides, while suc-rose is a disacchande, may also not be insignificant, in order to be absorbed as its constituent monosaccharides, sucrose must first be hydrolyzed by intestinal mucosal disaccharidases
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
Additionally, COR has a significant stimulating influence on intestinal disaccharidases
and alkaline phosphatases, and also significantly improve terminal digestive enzyme activities (Platel and Srinivasan, 2001a).
In rats, fed ginger (50 mg% for 8 weeks) enhanced pancreatic lipase activity was found (Platel and Srinivasan, 2000) and also enhanced intestinal lipase, disaccharidases
, sucrase and maltase activities (Platel and Srinivasan, 1996).
(lactase and maltase) are mainly secreted by small intestine mucosa and epithelium.
