<p>The acetolysis of carrageenan produces a polymer homologous series of oligosaccharides, [Gal α1,3 Gal, Gal β1,4 Gal], [Gal α1,3 Gal β1,4 Gal, Gal β14, Gal α1,3 Gal], [Gal α1,3 Gal β1,4 Gal α1,3 Gal, Gal β1,4Gal α1,3Gal β1,4Gal] etc. (Lawson, 1968). This is significant as it provides an entry to the α-gal series or Galili antigens due to the fact that the disaccharide Galα1,3 Gal can be isolated in quantity. The distribution of the full α-gal epitope (Galα1-3Galβ1-4GlcNAc-R) is unique in mammals, being abundantly expressed on glycoconjugates of non-primate mammals, prosimians and New World monkeys. In contrast, the α-gal epitope is not expressed on glycoconjugates of Old World monkeys, apes and humans; instead, they produce the natural anti-Gal antibody that specifically binds the α-epitope. Anti-Gal mediates the rejection of pig xenograft organs in humans and monkeys by binding α-gal epitopes on the pig cells, inducing complement mediated destruction and antibody dependent cell mediated destruction. This barrier to xenotransplantation has been eliminated by producing α1,3 glycosyltransferase to knockout pigs. Since anti-Gal is ubiquitous in humans, the α-gal epitope has clinical potential in the production of vaccines expressing α-epitopes that can be targeted to antigen presenting cells (APC), thereby increasing the immunogenicity of viral and other microbial vaccines (Macher, 2008).</p>

<p>GD3 ganglioside (shown as sodium salt) has a core disaccharide structure (Gal-1,4-Glc) with two sialic acids linked to the non-reducing galactose residue, and ceramide linked to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GD3 ganglioside is a minor ganglioside in most normal tissues but plays a crucial role in the development of the brain; its presence is significantly reduced in adults. However, expression of GD3 ganglioside is increased in pathological conditions, such as, cancers and neurodegenerative disorders (Malisan, 2002). GD3 ganglioside was the first cancer-associated ganglioside discovered, that promotes adhesion and invasion of cancers. GD3 ganglioside and GD2 ganglioside are highly expressed in a various malignant cancers and have become potential targets for next-generation cancer therapy (Liu, 2018).</p>
