title: Absorption of the indigestible disaccharide, β-1,4-mannobiose, from coconut by the rat portal vein.
abstract: The intestinal absorption of β-1,4-mannobiose by rats was investigated. Mannobiose was detected in the portal vein plasma by matrix-assisted laser desorption ionization/time of flight mass spectrometry after its administration to rats. The presence of mannobiose in the rat plasma was confirmed by an experiment using β-mannosidase. These results indicate that mannobiose was directly absorbed through the intestines even without being hydrolyzed.
