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 literature on Zymosan reveals few rigorous analytical studies on the detailed structure of this macromolecule due to the wide variation in extraction procedures reported. A hypothetical structure of the carbohydrate part of the molecule is shown below constructed from the available literature. This shows a β1,3 glucan chain with β1,6 branch points.

Pentagalacturonic acid (α-1,4 galacturonopentaose) is derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis (Combo, 2012). It is used in galacturonic acid metabolism research as a substrate to identify, differentiate and characterize endo- and exopolygalacturonase(s) and gluconase(s) (Jayani, 2005).

Gangliotetraose (Galβ1,3GalNAcβ1,4Galβ1,4Glc) is the core tetrasaccharide found in many gangliosides, such as, GM1 (Ledeen, 2009). Gangliosides containing gangliotetraose are abundant in mammalian brains, where they can cover 10%–20% of the total ganglioside mixture. They are found in epithelial membranes and are key elements for bacterial toxicity and viral infection, for example, it is the intestinal receptor for cholera toxin, the B-subunits of heat-labile toxin, rotavirus, and simian virus 40. They can function as neurotrophic and neuroprotective compounds, and have been used therapeutically for diabetic and peripheral neuropathies. They bind amyloid-β proteins and are involved in Alzheimer’s pathogenesis (Chiricozzi, 2020).

Anti-GQ1b ganglioside antibody is associated with Miller Fisher syndrome and is also found in patients with related conditions that may share the same pathogenic mechanism, such as, Bickerstaff brainstem encephalitis. Thus, the measurement of the anti-GQ1b antibody in suspected cases of Miller Fisher syndrome is a useful diagnostic marker (Paparounas, 2004). It has been found that GQ1b ganglioside contributes to synaptic transmission and synapse formation. Low concentrations of GQ1b ganglioside, evoked dopamine (DA) release from laboratory tissues (Chen, 2018).
