Abstract
Eight major oligosaccharides were isolated from platypus milk. By sequential exoglycosidase digestion and methylation study, their structures were elucidated as shown in Fig. 9 of this paper. The characteristics feature of the platypus milk oligosaccharides is that lacto-N-neotetraose and lacto-N-neohexaose are the major cores in contrast to human milk oligosaccharides in which lacto-N-tetraose and lacto-N-hexaose are found as the major core.
