Different Types Of Collagen
Scientists have currently identified over twenty-seven different types of collagen, and the first four are recognized as the most important. All types of collagen help prevent the body's tissues from stretching and sagging, and collagen comprises an estimated twenty-five percent of the total protein within the body. In addition to supporting the skin, it provides strength and structural support for tendons, bones, teeth, and internal organs. Type I collagen is the strongest form, and it helps in the formation of skin, tendons, blood vessel walls, and connective tissues. Type II collagen is a major component of cartilage, the connective tissue that protects joints, and it is also part of the structure of the ear, nose, bronchial tubes, and rib cage. Type III collagen is known as fibrillar collagen, and it is a key component of the skin and the body's major organs. It supports the functional integrity of the cardiac muscle. Other important types of collagen include type V and type X. Type V collagen assists the body in the formation of both cell surfaces and hair, and it is particularly important in the formation of the placenta during pregnancy. Also known as network-forming collagen, type X collagen exists mostly in cartilage, and it is recognized as a reliable marker for new bone growth in the cartilage that cushions joints.
