Answer 1

Correct answer is;

The carboxyl and sulphated groups in the glycosainoglycans.

Glycosaminoglycans (GAGs) are highly sulfated and linear polysaccharides that have various biological functions. GAGs are classified into four groups: heparan sulfate (heparin), chondroitin sulfate (dermatan sulfate), keratan sulfate, and hyaluronan, GAGs are classified on the basis of of different repeating disaccharide units.

large amounts of chondroitin sulfate and keratan sulfate found and play a crucial part in the cartilage hydration. Due to hydration cartilage have a gel-like properties and consequently, resistance to deformation.

Because of high viscosity and low compressibility, GAGs (hyaluronic acid) are acts as lubricating fluid in the joints.
