Drugs such as acarbose and natural supplements like l-arabinose impede the activity of alpha-glucosidases such as sucrase and slow absorption.
Instead, combination (1:1) of both showed activation of sucrase. Sucrose binds to the active site on sucrase, and this puts stress on the bond between the two sugars that make up sucrose.
Brush border enzymes include lactase (which breaks down lactose), sucrase (which breaks down sucrose), and maltase (which breaks down maltose).
Of 203 children (mean age, 11.5 years) with chronic abdominal pain who presented to the gastroenterology clinic at Children's Hospital of Wisconsin, the proportion with abnormally low disaccharidase levels in small-intestinal biopsy samples was 37% for lactase, 21% for sucrase, 25% for glucoamylase (which cleaves glucose from maltose or starch), and 8% for palatinase (sucrase-isomaltase).
It is documented that phytate decreased the activities of disaccharidas, Na+K+-ATPase, and glucose concentrations in chickens intestine, but phytase enhanced the concentrations of amylase, sucrase, maltase, Na+K+-ATPase, and glucose (Liu et al., 2008b).
Alpha glucosidase (sucrase or maltase) inhibition % was calculated as (1 - [([A.sub.sample] - [A.sub.blank])/([A.sub.control] - [A.sub.blank])]) * 100.
