That depends a bit on what your proteoglycans are and where in the body they are. I'm currently working the musculoskeletal field. I'm pretty sure I've seen it suggested that proteoglycans can act as lubricators and allow fibrils within organs such as tendons to slip past each other smoothly. I also know that the large proteoglycan aggrecan is a vital component of hyaline cartilage. It contains lots of negatively charged polysaccharide side chains which attract and retain water. This contributes to cartilage's ability to resist compressive forces.
Organic, for sure.
Basal Lamina
Actually, proteoglycans are conjugates of proteins and carbohydrates in which there is more carb and less protein. In fact, proteoglycans have GAGs (heteropolysaccharides) as carbohydrates. Glycoproteins, on the other hand, have more protein and less carb. Here, carbohydrates are in the form of Oligosaccharides.
Dentine and cementine contain specific proteins as proteoglycans, collagene and other.

Proteoglycans are organic compounds !
hydrated proteoglycans
YEs, it does..
Organic, for sure.
proteoglycans - heaprin sulfate , chondroitin sulfate , keratan sulfate , GAG's Non-proteoglycans - Hyaluronic acid collagen , elastin , fibronectin , laminin
glycoproteins
[protein molecules and] carbohydrate molecules.
due to sulfated proteoglycans

Anulus Fibrous
Cartilage has bone marrow, so therefore it connects bones to bones in the skeletal system.
