<p>GD2 (shown as sodium salt) has a core trisaccharide structure (GalNAc-b-1,4-Gal-b-1,4-Glc) with its two sialic acids linked b-2,3/b-2,8 to the inner galactose residue and ceramide linked to position 1 on the reducing terminal glucose residue. 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 is overexpressed in a number of tumors, including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, it 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>Mixed DP 7/8 Na galacturonans (α-1,4 galacturonoheptoses and octaoses), 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 characterized endo- and exopolygalacturonase(s), and gluconase(s). The addition of very short fragments of homogalacturonan oligosaccharides, restores development in dark-grown, de-etiolated seedling mutants, suggesting that they are unable to generate de-methylesterified pectin fragments. A model of spatiotemporally separated photoreceptive and signal-responsive cell types has been proposed, that contains overlapping subsets of the regulatory network of light-dependent seedling development.</p>
