Chondroitin sulfate A, also known as 4-chondroitin sulfate, is an acidic mucopolysaccharide composed of (1→4) -O-β-D-glucopyranuronic acid and (1→3) -2-n-acetylamino-2-deoxy-4-o-sulfate-β-d-galactopyranose repeat units. It is one of the components of connective tissue matrix and a cogroup of glycoprotein.
Chondroitin sulfate A changes with age in organisms, from birth to old age, its content gradually decreases, while Chondroitin sulfate C increases.
CSA can enhance the activity of lipase, decompose the triglycerides in chylomicrons into fatty acids, reduce and clarify the chylomicrons in the blood, and also has anticoagulation and antithrombotic effects.
