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 α 1 → 2Gal β 1 → 4Glc Gal α 1 → 3Gal β 1 → 4Glc Gal 2b 1 → 4GlcNAc 2b 1 → 3Gal β 1 → 4Glc Fuc α 1 → 2Gal β 1 → 4GlcNAc β 1 → 3Gal β 1 → 4Glc Gal α 1 → 3Gal β 1 → 4GlcNAc β 1 → 3Gal β 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.
