vn1 ( oligosaccharides greater than 2 000 dalton ) apparently represented a mixture of saccharides derived from complex , n-glycosidically linked glycans ( molar ratio man/glcnac/gal 3:4:8 ) , while fractions vn2 ( tetra- to hexasaccharides ) , vn3 ( trisaccharide ) and vn4 ( disaccharide ) were free of mannose , but did contain all the n-acetylgalactosamine released from the protein as its alditol .
