<p>GD1b ganglioside (shown as ammonium salt) is one of the major gangliosides in neuronal and glial membranes. It has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the inner galactose residue, and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GD1b ganglioside acts as a receptor for BK virus, as well as for heat-labile LTII-a toxin, produced by enteropathogenic E. coli. GD1b ganglioside also interacts with tetanus neurotoxin (TeNT) and is crucial for its entry into cells (Kolter, 2012). The functional significance of ammonia in the brain is not yet fully understood: see (Modi 1994).</p>

<p>1,3-a-1,6-a-D-Mannotriose 1-O-propylamine acetate salt is a modified oligosaccharide. It has been synthesized by the reaction of 1,3-a-1,6-a-D-mannopyranosyl bromide with proline amine acetate. This product is 98% pure and can be used as a complex carbohydrate in research or as a food additive. The CAS number for this product is 712092-14-8.</p>

<p>Tri-guluronic acid sodium salt (1,4-linked α-L-sodium guluronotriose) is one of a number of oligosaccharides obtained from alginate which is a polysaccharide in brown seaweeds containing: blocks of repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences. This oligosaccharide can be released by acid hydrolysis (Shimokawa, 1996) and a number of biological activities have been discussed in a recent review (Xing, 2020).</p>

1-Deoxy-1-morpholino-D-fructose is a drug that has been shown to have an inhibitory effect on the production of dinitrophenol, leading to a decrease in the level of reactive oxygen species. The drug binds to lysine residues of proteins and forms adducts with physiological function. 1-Deoxy-1-morpholino-D-fructose also inhibits human serum albumin concentration, which may be due to its ability to inhibit oxidative DNA damage. This drug has been shown to be effective in vivo for treating autoimmune diseases and diabetes.

Lactose-6'-phosphate is a sugar phosphate

Melezitose is a non-reducing trisaccharide that is produced by many plant sap-consuming insects, such as aphids (e.g. Cinara pilicornis).  Melezitose is a component of honeydew which acts as an attractant for ants and also as food for bees. Partial hydrolysis of melizitose releases glucose and turanose, an isomer of sucrose.

CO2-philic compound; used in pharmaceuticals and CO2-based processes

Lipopolysaccharides are a heterogeneous group of molecules that include endotoxins, lipid A, and core oligosaccharide. They are released from the cell wall of gram-negative bacteria as a result of bacterial lysis. Lipopolysaccharides are potent activators of immune cells, inducing the secretion of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). TNF-α is also known to induce the production of other pro-inflammatory cytokines including IL-6, IL-8, IL-10, and IL-12. Lipopolysaccharides have been shown to cause liver damage in animals by increasing plasma alanine aminotransferase levels. This may also be due to their ability to induce the production of malondialdehyde and c-reactive protein.

GM2 ganglioside (sodium salt) has a core trisaccharide structure (GalNAcβ1,4Galβ1,4Glc) with sialic acid linked α2,3 to the central galactose residue and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GM2 ganglioside is present on neuronal cells and plays a key role in the regulation of dendritogenesis in cortical pyramidal neurons. In lysosomal storage disorders, such as, Tay-Sachs and Sandhoff disease, where hexosaminases A and B are deficient, GM2 ganglioside accumulates in the nervous system (Cachon-Gonzalez, 2018). GM2 ganglioside is also overexpressed in melanomas and other tumours of neuro-ecto origin (Yoshida, 2020). Moreover, the sugar moiety of the GM2 ganglioside is a receptor allowing the viral infection of cells with reovirus and rotavirus (Zhu, 2018).

<p>Asialylated glycosphingolipid and precursor for ganglioside biosynthesis. The compound is a major glycosphingolipid in human neutrophils and is involved in the regulation of superoxides as well as nitric oxide. Moreover, lactosylceramide accumulates in atherosclerotic plaques and is also found elevated in familial hypercholesterolemia and polycystic kidney disease. Animal studies revealed that lactosylceramide induces hypertrophy in cardiomyocytes via signal transduction pathway that is oxygen-sensitive.</p>

Hyaluronic acid is a polysaccharide containing repeating disaccharide units of β-1,3-N-acetyl glucosamine and β-1, 4-glucuronic acid. A series of unsaturated oligosaccharides (oligouronic acids) are released from hyaluronic acid by the action of hyaluronidase on the umbilical cord (Weissman, 1954). This octasaccharide ammonium salt and other enzymatically produced polymer homologs have been of value in the study of hyaluronic acid metabolism in both healthy and diseased tissues (Hascall, 2019).
