Answer:
Proteins and polysaccharides.
Explanation:
Proteoglycans are heavily glycosylated proteins. These proteoglycans are present in the extracellular matrix of the animal cells and acts as a lubricant for the cells.
Proteoglycans are proteins that are covalently bonded with muco polysaccharidse. Proteoglycans are formed by the bonding between proteins and carbohydrates ( polysaccharides). Proteoglycans can combine with collagen to form cartilage and may affect the stability of a protein.
Thus, the correct answer is option (E).
