    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).
