Patent ID: 8617631

Claim:
An oligosaccharide ingredient comprising glycosylated amino acids and peptides of the general formula R n Sac m wherein R is an amino acid residue, Sac is a monosaccharide selected from the group consisting of N-acetyl-neuraminic acid, N-acetyl galactosamine and galactose, n has a value of between 1 and 10 with the proviso that if n has the value 1 R is a threonine residue or a serine residue and if n has a value of between 2 and 10 the peptide contains at least one threonine or serine residue, m has a value of between 2 and 4 and at least 20 mol % of the ingredient is N-acetyl-neuraminic acid, wherein the oligosaccharide ingredient has at least one glycosylated amino acid selected from the group consisting of NeuAc-Î±-2,3-Gal-Î²-1,3-(NeuAc-Î±-2,6-)-GalNAc-R n , NeuAc-Î±-2,3-Gal-Î²-1,3-GalNAc-R n , Gal-Î²-1,3-(NeuAc-Î±-2,6-)-GalNAc-R n , and Gal-Î²-1,3-GalNAc-R n .
