Function of collagen
Collagens can be found in the extracellular matrix -an intricate network of macromolecules that determine the physical properties of body tissues.
In the middle layer of the skin -the dermis -collagen helps form a fibrous network, upon which new cells can grow. Collagen is also required in the replacement and restoration of dead skin cells. Some collagens also function as protective coverings for delicate organs in the body such as the kidneys.
