Figure 12.15 Gangliosides. The prefix mono-, di, tri- or tetra- denotes the number of sialic acid W-acetyl neuraminic acid, NANA) residues present in the molecule. The many different gangliosides have complex structures and for convenience shorthand notations are used. The two commonest were introduced by Svennerholm, who named the parent compound GM1, and Wiegnandt, who named it Ggnti. The latter system gives enough information for the structures to be worked out from the shorthand form once the symbols have been learnt. GalNAc represents N-acetyl galactosamine in the above structure.

Synthesis of an adriamycin-HPMA copolymer-galactosamine conjugate is shown in Fig. 10. Attachment/release points at the side-chain termini are created by incorporation of tailor-made comonomers into the copolymer structure.

Mucopolysaccharides are some of the most common structural carbohydrates in cestodes, although little is known of their biochemistry or function. They are heteropolymers and contain amino sugars (e.g. glucosamine, galactosamine) and uronic (glucuronic, galacturonic) acids. Often, mucopolysaccharides are complexed with proteins to form mucoproteins or glycoproteins, which, as discussed in Chapter 2, are major components of...
