The main components of the cartilage matrix are as follows: 1. It is collagen. Collagen, both in bone and cartilage, is widely available and is an important organic component within it. The collagen is arranged horizontally or crosswise to give the cartilage some toughness and strength to withstand a variety of stresses. 2, is the proteoglycan. The content of proteoglycans inside cartilage is relatively small, but it is this relatively small amount of proteoglycans, for cartilage related to nutrition and maintenance of the shape are important. If the cartilage is deficient in proteoglycans, then the wear and tear of the cartilage may increase.3. Bone salts in the cartilage matrix. These bone salts are also known as inorganic substances, which are salts like calcium, phosphorus and magnesium. Such inorganic substances can effectively enhance the strength of cartilage. The cartilage matrix also contains a large amount of water.
