title: Chemical characterisation of the oligosaccharides in a sample of milk of a white-nosed coati, Nasua narica (Procyonidae: Carnivora).
abstract: Carbohydrates were extracted from a sample of coati milk and the component oligosaccharides were separated and partially purified by gel filtration and preparative thin layer chromatography. Their structures were determined by 1H-NMR. Fuc alpha 1-->2Gal beta 1-->4Glc Gal alpha 1-->3Gal beta 1-->4Glc Gal beta 1-->4GlcNAc beta 1-->3Gal beta 1-->4Glc Fuc alpha 1-->2Gal beta 1-->4GlcNAc beta 1-->3Gal beta 1-->4Glc Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->3Gal beta 1-->4Glc The two pentasaccharides are novel sugars. In addition, higher oligosaccharides, whose core units were lacto-N-neohexaose, were found in coati milk. Free lactose constituted only about one-third of the total free milk saccharides. The results are discussed in terms of comparisons with the milk sugars of bears and other species.
