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.

Is proteoglycans organic or inorganic?
Organic, for sure.
This layer of the filtration membrane is composed of collagen fibers and proteoglycans in a glycoprotein matrix?
Basal Lamina
What is the difference between a glycoprotein and a proteoglycan?
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.
What proteins can be found in the human tooth structure?
Dentine and cementine contain specific proteins as proteoglycans, collagene and other.

Is proteoglycans organic or inorganic?
Organic, for sure.
What is the chemical composition of the matrix in cartilage?
proteoglycans - heaprin sulfate , chondroitin sulfate , keratan sulfate , GAG's Non-proteoglycans - Hyaluronic acid collagen , elastin , fibronectin , laminin
Proteins with sugar molecules attached to them are called what?
glycoproteins
Glycoproteins and proteoglycans are combinations of proteins and?
[protein molecules and] carbohydrate molecules.
Why matrix of hyaline cartilage appears basophilic?
due to sulfated proteoglycans

Which part of the vertebral column do you think would be most directly impacted by a reduction in proteoglycans?
Anulus Fibrous
What is the function of a cartilage cell?
Cartilage has bone marrow, so therefore it connects bones to bones in the skeletal system.
