Chondroitin sulfate, major component of cartilage is part of a large protein molecule called, proteoglycan composed of repeated units of glucosamine sulfate, that gives cartilage elasticity.
Chondroitin sulphate attracts water into the cartilage matrix and stimulates the production of cartilage, it has the ability to prevent enzymes from dissolving cartilage.
Animal studies have shown chondroitin effectively promotes the healing of bone. Chondroitin sulfate has also been shown to help people with osteoarthritis by playing a role in joint function and repair.
Chondroitin sulfate is an acidic polymer consisting of repeating D-glucuronic acid and D-N-acetylgalactosamine units, and the N-acetylgalactosamine is substituted with the sulfate at either the 4' or 6' position, with approximately one sulfate being present per disaccharide unit. Absorption of chondroitin sulfate is lower than that of glucosamine (10% to 15% versus 90% to 98%).
Extracted from animal cartilage, such as tracheas or shark cartilage.
