title: Chemical characterization of milk oligosaccharides of the brown bear, Ursus arctos yesoensis.
abstract: Two tri-, two hexa- and two deca-saccharides were isolated from bear milk by chloroform/methanol extraction and gel filtration. The oligosaccharides were characterized, mainly by 1H-NMR, as follows: [structures: see text]. Both trisaccharides were present in bear milk at a higher concentration than lactose.
