In extracellular matrix Collagen & Elastin is present.
Collagen is for strength & Elastin is for elastisity?
So why 2? Is there any another molecule acting as both?
collagen is needed for resistance to stretchforces (tissue strength) elastin is needed for recoiling of the tissue to the original stat after deformation.
–> these two have different function so both are needed.
and no, there is no one molecule that can do both as good as these two molecules do them individually…
