Type II collagen is the basis for articular cartilage and hyaline cartilage, formed by homotrimers of collagen, type II, alpha 1 chains.
It makes up 50% of all protein in cartilage and 85–90% of collagen of articular cartilage.
Type II collagen does form fibrils. This fibrillar network of collagen allows cartilage to entrap the proteoglycan aggregate as well as provide tensile strength to the tissue. Oral administration of native type II collagen induces oral tolerance to pathological immune responses and may be useful in arthritis.
