Cartilage is a firm but flexible connective tissue found in human joints, the nose, ears, and the rings of the trachea (windpipe). It contains a specific protein that gives it its unique properties.
Main Protein: Chondrin / Chondroitin (a proteoglycan).
Fibers: Collagen (provides strength) and elastic fibers (in elastic cartilage).
Location: Joints, nose, ears, trachea, and intervertebral discs.
The protein found in cartilage is Chondrin (also known as Chondroitin).
More specifically, cartilage is composed mainly of:
There are three main types of cartilage:
The main protein found in cartilage is Chondrin (Chondroitin sulfate), along with Collagen fibers. Chondroitin provides resilience and flexibility while collagen provides tensile strength.
