Question

Proteoglycans are a group of macromolecules formed from: a. proteins and glycosaminoglycans. b. proteases and glycosaminoglycans. c. proteins and glycogen. d. proteases and monosaccharides. e. proteins and polysaccharides.

Answer 1

a

Step-by-step explanation:

Answer 2

Proteins and polysaccharides.

Step-by-step 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).
