Application

4-O-β-Galactopyranosyl-D-mannopyranose (2-epi-Lactose, 2-epilactose), a nondigestible epimer of lactose, may be used to study its value as a prebiotic sugar that promotes intestinal mineral, especially calcium, absorption.

Epilactose (4-O-β-D-galactopyranosyl-D-mannose), an epimer of lactose, is a rare disaccharide existing extremely small quantities in heat-treated milk, in which epilactose is produced by non-enzymatic catalysis from lactose. This disaccharide is a kind of non-digestible carbohydrate, has a good prebiotic effect

We previously showed that epilactose, a nondigestible disaccharide, increased calcium (Ca) absorption in the small intestines of rats. Here, we explored the mechanism(s) underlying the epilactose-mediated promotion of Ca absorption in a ligated intestinal segment of anesthetized rats. The addition
