The nondigestible disaccharide epilactose increases paracellular Ca absorption via rho-associated kinase- and myosin light chain kinase-dependent mechanisms in rat small intestines.
J. Agric. Food Chem. 58(3) , 1927-32, (2010) 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 seg... |

Recent advances on physiological functions and biotechnological production of epilactose.
Appl. Microbiol. Biotechnol. 97(5) , 1821-7, (2013) 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... |

Biochemical characterization of a thermophilic cellobiose 2-epimerase from a thermohalophilic bacterium, Rhodothermus marinus JCM9785.
Biosci. Biotechnol. Biochem. 75 , 2162-2168, (2011) Cellobiose 2-epimerase (CE) reversibly converts glucose residue to mannose residue at the reducing end of β-1,4-linked oligosaccharides. It efficiently produces epilactose carrying prebiotic properties from lactose, but the utilization of known CEs is limited... |

Prebiotic properties of epilactose.
J. Dairy Sci. 91(12) , 4518-26, (2008) We recently reported that cellobiose 2-epimerase from Ruminococcus albus effectively converted lactose to epilactose. In this study, we examined the biological effects of epilactose on intestinal microbiota, bile acid metabolism, and postadministrative plasma... |

Effects of epilactose on calcium absorption and serum lipid metabolism in rats.
J. Agric. Food Chem. 56(21) , 10340-5, (2008) Epilactose (4-O-beta-galactopyranosyl-D-mannnose) is a rare disaccharide in cow milk that can be synthesized from lactose by the cellobiose 2-epimerase of Ruminococcus albus. In this study, we examined the biological activities of epilactose using male Wistar... |

[Ion chromatographic determination of lactulose and epilactose in the presence of lactose and other carbohydrates in milk and milk products].
Z. Lebensm. Unters. Forsch. 181(5) , 408-11, (1985) A method is described for the analysis of carbohydrates in milk and milk products which develop during heat treatment. It is based on the separation of their borate complexes by anion exchange chromatography using two optimized buffer systems. A reliable qual... |

Effect of high pressure on isomerization and degradation of lactose in alkaline media.
J. Agric. Food Chem. 51(7) , 1894-6, (2003) The combined effects of temperature (60 degrees C) and high-pressure treatments (400 MPa for 3 h) on the isomerization-degradation of lactose (10%) in basic media were studied. The formation of isomeric disaccharides (lactulose and epilactose) and galactose d... |

Ingestion of epilactose, a non-digestible disaccharide, improves postgastrectomy osteopenia and anemia in rats through the promotion of intestinal calcium and iron absorption.
J. Agric. Food Chem. 58(19) , 10787-92, (2010) Gastrectomy often results in osteopenia and anemia because of calcium (Ca) and iron (Fe) malabsorption. Here, we investigated the effects of feeding epilactose, a non-digestible disaccharide, on gastrectomy-induced osteopenia, anemia, and Ca and Fe malabsorpt... |

Immobilization of a thermostable cellobiose 2-epimerase from Rhodothermus marinus JCM9785 and continuous production of epilactose.
Biosci. Biotechnol. Biochem. 76(8) , 1584-7, (2012) Cellobiose 2-epimerase (CE) efficiently forms epilactose which has several beneficial biological functions. A thermostable CE from Rhodothermus marinus was immobilized on Duolite A568 and packed into a column. Lactose (100 g/L) was supplied to the reactor, ke... |

Regioselectivity in beta-galactosidase-catalyzed transglycosylation for the enzymatic assembly of D-galactosyl-D-mannose.
Biosci. Biotechnol. Biochem. 68(10) , 2086-90, (2004) The regioselectivity of beta-galactosidase derived from Bacillus circulans ATCC 31382 (beta-1,3-galactosidase) in transgalactosylation reactions using D-mannose as an acceptor was investigated. This D-mannose associated regioselectivity was found to be differ... |
