Abstract
Two trisaccharides, and a pentasaccharide were obtained from bovine colostrum. Their chemical structures were determined by using methylation and 13C-NMR analyses as follows: GalNac alpha 1-3Gal beta 1-4Glc, Gal alpha-1-3Gal beta 1-4Glc, GaL beta 1-3[Gal beta 1-4GlcNAc beta 1-6]Gal beta 1-4Glc. GalNAc alpha 1-3Gal beta 1-4Glc, which was identified in this study, is a novel oligosaccharide from natural sources. Gal alpha 1-3Gal beta 1-4Glc and Gal beta 1-3[Gal beta 1-4GlcNAc beta 1-6]Gal beta 1-4Glc (lacto-N-novopentaose) have been already found in ovine colostrum, and in horse colostrum and marsupial milk, respectively.Entities:
