<p>Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. A number of publications have suggested that agarodecaose has properties that include: anti-microbial, antiviral, prebiotic, anti-tumoral, immunomodulatory, anti-inflammatory, glucosidase inhibitory, and hepatoprotective properties.</p>

<p>3',4'-O-Carbonyl-6,6'-di-O-tert-butyldiphenylsilyl lactal is a synthetic oligosaccharide that has been modified with a click modification. It is comprised of 3 different monosaccharides, one saccharide, and one carbonyl group. This carbohydrate is synthesized from the natural sugar D-ribose, which is modified with an O-tert-butyldiphenylsilyl lactal. The synthesis begins with the addition of a methyl group to the sugar's primary hydroxyl group. Then the sugar is reacted with fluorine gas to form an ether bond between the sugar's primary hydroxyl and its secondary hydroxyl. The final step in the synthesis involves glycosylation of the terminal hydroxyl groups on each monosaccharide.</p>

<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 umbilical cord (Weissman, 1954). This hexasaccharide and other enzymatically produced polymer homologs have been of value in the study of hyaluronic acid metabolism in healthy and diseased tissues (Hascall, 2019).</p>

<p>GT2 oligosaccharide (free acid) has a core trisaccharide structure (GalNAcβ1,4Galβ1,4Glc) with three sialic acid residues (NeuAc) linked α2,8/α2,8/α2,3 to the inner galactose residue (Ledeen, 2009). GT2 oligosaccharide is the carbohydrate moiety in the GT2 ganglioside. A key role has been reported for gangliosides, such as, GT1b and GT2 as modulators in the interaction between microglia (resident cells of the brain that regulate brain development) and brain tumors. It is possible that they will be important targets for therapeutical intervention in the near future (Daniele, 2020). In addition, C-series gangliosides, such as GT3, GT2, GQ1c, and CP1c are expressed in normal pancreatic tissue but are practically lost in the pancreas of diabetic animals (Saito, 1999).</p>

<p>Melibiulose is a dietary supplement that has been shown to help maintain the health of the human immune system. It has also been shown to stimulate prostate cancer cells. Melibiose, the sugar molecule found in melibiulose, has been found to be processed by toll-like receptor 2 and 4, which are proteins found on the surface of immune cells. The glycan structure of melibiose may be responsible for its conditioning effects as it binds to proteases and surfactants, preventing them from binding to other molecules. This ternary complex prevents glycosylation reactions and reduces viscosity in detergent compositions.</p>
