<p>Tetra-guluronic acid sodium salt (1,4-linked α-L-sodium guluronotetraose) is one of a number of oligosaccharides obtained from alginate, a polysaccharide from brown seaweeds. It contains 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 and a number of biological activities have been discussed in a recent review.</p>

<p>GD2 oligosaccharide is the core trisaccharide structure of the ganglioside GD2 (sodium salt) (GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the central galactose residue (Ledeen, 2009). GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 ganglioside is overexpressed in a number of tumors, including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, GD2 ganglioside has been found in low concentrations on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state) and tumor-initiating capabilities. It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).</p>

<p>The compound 4-Methoxyphenyl 4-O-(3,6-di-O-benzyl-2-deoxy-4-O-levulinoyl)-2,3,4,6-tetra‑O‑benzyl‑a‑L -fucopyranosyl)-2,3,4,6‑tetra‑O‑benzyl‑a‑L -fucopyranoside is a glycoside of the monosaccharide 2,3,4,6 tetra O benzyl a L fucopyranose. It is prepared by the reaction of methyl 4 methoxyphenol with 2 deoxy 4 levulinoyl 2 phthalimido b D glucopyranoside in the presence of an acid catalyst. The compound has been shown to have anti inflammatory and anti allergic effects.</p>

<p>3-Fucosyllactose (3-FL) is a small and neutral human milk oligosaccharide (HMO) that is metabolized by bacteria in the large intestine.

<p>Mixed DP 10-15 Na galacturonans (α-1,4 10-15 Na galacturonans) are derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis. They are used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s) and gluconase(s). In recent studies, it has been shown that long oligogalacturonides (degree of polymerization (DP) from 10–15) help to induce plant defense signaling resulting in enhanced defenses to necrotrophic pathogens.</p>
