Transcribed Image Text:

Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called proteoglycan. (a) Which of the following are possible components of glycosaminoglycans? Select all that apply. Bo-fructofuranose N-acetylgalactosamine uronic acid amylose (b) Determine which aof the following statements about glycosaminoglycans are true. There is more than one true statement; select all the true statements. Because glycosaminoglycans consist of only two residues, they generally have low molecular weights. Glycosaminoglycans contain a high negative charge density, which enables interaction with the aqueous environment. Glycosaminoglycans are homopolysaccharides composed of repeating glucosamine or galactosamine residues. Hyaluronan (hyaluronate) and keratan sulfate are examples of glycosaminoglycans. Cellulose is an example of a glycosaminoglycan. O OO Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness.
