- From which two monosaccharide units is the repeating disaccharide unit of chondroitin 6-sulfate derived?arrow_forwardAn oligosaccharide is a repeating unit of a-D-galactopyranosyl-(a-1 >3)-allopyranoside. Each disaccharide unit is linked via B-1 --->4 glycosidic bond. The oligosaccharide has 10 monosaccharide residues. Required: Is this oligosaccharide a good substrate for glycolysis? Why or why not? Provide two reasons and discuss corn prehensively.arrow_forwardPolysaccharides may gel through a variety of different mechanisms. Which of these statements is FALSE? Select one: O a. Alginate gels through the formation of calcium salt bridges between G-blocks O b. Xanthan gum gels through the formation of hydrophobic interactions between non-polar regions on the chain O c. Kappa-Carrageenan gels through the formation of potassium ion bridges between sulfate groups O d. High methoxy pectin forms gels at acidic pH values and high sugar contents because of a reduction in electrostatic repulsion and the generation of a strong osmotic attraction.arrow_forward
