We have isolated a nonfucosylated and three variously fucosylated neutral oligosaccharides from human milk that are based on theiso-lacto-N-octaose core. Their structures were characterized by the combined use of electrospray mass spectrometry (ES-MS) and NMR spectroscopy. The branching pattern and blood group-related Lewis deter-minants, together with partial sequences and linkages of these oligosaccharides, were initially elucidated by high-sensitivity ES-MS/MS analysis, and then their full structure assignment was completed by methylation analysis and 1 H-NMR. Three new structures were identified....
