What is ground substance? Name its components. |
Ground substance consists of gigantic proteoglycan complexes that fill the space between collagen fibers.
Specifically the proteoglycan has protein groups called chondroitin sulfate and keratan sulfate. These stick onto a core protein which is anchored to hyaluronic acid by link proteins.
The sulfate groups impart a negative charge, making this molecule well hydrated to form a gel. |
