11. (10.1) describe glycosamino- The most abundant type of polysaccharide
glycan in the extracellular matrix (ECM) of animals,
consisting of repeating disaccharide units
that give a gel-like character to the ECM.

12. (10.1) define proteoglycan A long, linear core protein with many GAGs
attached to it; found in the ECM.

13. (10.1) describe chitin A tough, nitrogen-containing, polysaccha-
ride polymer that forms the external skele-
ton of many insects and crustaceans and is
found in the cell walls of fungi.
