What is the main GAG found within the vitreous?

Explanation:
In the vitreous, the gel-like consistency comes from a network where a non-sulfated glycosaminoglycan binds water to create a hydrated matrix. Hyaluronic acid does this job, binding large amounts of water and forming a viscous, transparent gel that works with collagen fibers to maintain structure and clarity in the vitreous. The other GAGs listed are sulfated and contribute to proteoglycans in various tissues, but they do not provide the primary hydrated gel of the vitreous.
