*The article was translated into English using automatic translation. The editors are working on its improvement.
Elastin is a fibrillar (thread-like) protein in human connective tissue. It provides elasticity to the skin due to its high strength fibers, which have the ability to stretch and then return to their original state after stress.
Elastin molecules include approximately 800 amino acid residues, have a globule shape and a diameter of 2.8 nm. They are connected into fibrous strands using rigid cross-links. The structure of the fibers includes glycoproteins that influence the spatial organization of molecules.
With the help of fibrillar protein, our skin is capable of regenerating scratches, burns or wounds. The peak of its active production occurs at 20-25 years. It is during this period that postoperative wound healing and inflammation occur best.
Elastin does not dissolve in cold and hot water; it is highly resistant to acids and alkalis.
