about two thirds of the internal glcnac residues in these glycans are substituted by fuc ( alpha 1 -- -- 6 ) , all the triantennary species carry the third gal ( beta 1 -- -- 4 ) glcnac ( beta 1 -- -- unit at the man ( alpha 1 -- -- 6 ) -branch , and roughly one fourth of the n-acetyllactosamine units in the non-intersected biantennary oligosaccharides are incomplete .
