The following is an example of an O-linked oligosaccharide chain in oligosaccharide is linked to the protein by the side-chain functional B the side-chain functional group of serine or threonine residues. Fuda2-12) Gal(β1-34)GlcNAc(B1-4) aride chain in glycoproteins. The O-linkage means the GlcNAc(a1 )-) Serine GalNAc(al>3) al(B1- 4)GIcNAc(B13) Gal(B1->4)GIcNAc(3)G1>3) Fuc(a22) Draw out this polymer from the following Fischer projections of the monosaccharide. 1) Show each monosaccharide in the Haworth projection and in the Chair conformation for the six-member rings. 2) Show...
