<p>Zymosan is prepared from the cell walls of baker's yeast (Saccharomyces cerevisiae) and consists of polysaccharide chains of various molecular weights, containing approximately 73% polysaccharide, 15% protein, 7% lipid and other inorganic components. When injected into animals, it induces inflammation and has been used for many years in inflammation and immunology research. The conditions activated include components of the complement system, prostaglandins and leukotrienes, platelet aggregation factor, and lysosomal enzymes. Zymosan preparations are often insoluble but can be made soluble for separation on DE cellulose or Sepharose to produce more active fractions.</p>

<p>2-Acetamido-3-O-(2-acetamido-2-deoxy-a-D-galactopyranosyl)-2-deoxy-D-galactopyranose is a glycan that is found in human serum and maternal blood. The wild type strain of 2,3,4,6,7,8<br>diacetylgalactosaminyltransferase (GnTIII) gene has been shown to be essential for the synthesis of this glycan. This glycan is also found in the carcinoma cell lines HT1080 and SW480. Structural analysis of the glycan has revealed that it contains a hydroxyl group on the C1 position and an acetamido group on the C2 position. Glycans are polymers that play roles in many biological functions such as cell recognition, immune responses, and carbohydrate metabolism. The structure of this glycan was studied using titration calorim</p>

<p>Chitopentaose is a pentaacetyl derivative of the sugar chitohexaose. It is an oligosaccharide that has been shown to inhibit the activity of glycosidases and lectins, which may be due to its high affinity to these enzymes. Chitopentaose has also been found to bind to insulin receptors in the human tumor cell line A-20, leading to a reduction in tumor growth. The molecule also inhibits the transcriptional regulation of genes encoding for penicillin-binding protein, mouse tumor necrosis factor, and α1-acid glycoprotein.</p>

<p>GM1b pentasaccharide (sodium salt) has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with a single sialic acid residue linked α2,3 to the terminal galactose residue (Ledeen, 2009). GM1b oligosaccaharide is the carbohydrate moiety in GM1b ganglioside, which is a minor component of human brain monosialoganglioside fraction. GM1b ganglioside and especially anti-GM1b IgG antibodies are associated with axonal Guillain-Barré syndrome, which develops following C. jejuni infection (Yuki, 1999).</p>
