What is Collagen?

Collagen in the skin

THE COLLAGEN MOLECULE

Collagen is the main structural protein of the different connective tissues present in animals.  It is mostly found in fibrous tissues, such as tendons and ligaments, and is also abundant in corneas, cartilage, bones, blood vessels, the gut, and intervertebral discs.

Collagen is the major insoluble fibrous protein found in the extracellular matrix of the skin, together with elastin and hyaluronic acid.  The collagen family consists of 28 different proteins which account for 25% – 35% of the total protein mass in mammals and play a pivotal role in the structure of several tissues, such as skin and bones, providing rigidity and integrity.
