<p>a1,3-Galactobiosyl b-methyl glycoside is a fluorinated saccharide that possesses the same chemical structure as N-acetylgalactosamine. It has been synthesized by click modification with methyl iodide and methyl bromoacetate. The synthesis of this compound was achieved by glycosylation of galactose with 1,3-diiodo-2,2'-bithiopropane followed by methylation of the resulting glycosylation product with methyl bromoacetate to form the desired compound. This carbohydrate can be used in a variety of applications including anti-inflammatory drugs, antibiotics, and cancer treatments.</p>

<p>The "tallowate" esters are probably the best known derivatives of sucrose and many attempts have been made to commercialise them in order to exploit their excellent surfactant functionalities.  The most functional products are the mono- and diesters of the tallow acids (stearic, palmitic, oleic) with hydrophile-lipophile balance (HLB) values that lend themselves to surfactant applications in foods and cosmetics.  They also have other uses, for example in coating fruits with a semipermeable membrane that acts as a preservative.  Manufacturing economics have prevented these products from mass production and they remain in niche applications.</p>

<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>
