How does it work?
A proteoglycan consists of a long protein (polypeptide) with many side polysaccharide chains attached to it. The attached side chains are polysaccharides—chiefly chondroitin sulfate and keratin sulfate. Glucosamine is a key component of keratin sulfate and hyaluronic acid. Galactosamine is a key amino sugar in chondroitin sulfate. Glucosamine sulfate provides sulfur in the form of sulfate, a key component of both chondroitin sulfate and keratin sulfate found in bone and the cornea.
