Introduction
Elastin is a key structural protein found in the extracellular matrix of connective tissues. It provides resilience and elasticity to tissues such as the skin, lungs, and blood vessels, allowing them to stretch and recoil efficiently. While it is less abundant than collagen, elastin plays a critical role in maintaining the structural integrity and function of various organs.
Structure of Elastin
Elastin is primarily composed of the protein tropoelastin, which is synthesized by fibroblasts and smooth muscle cells.
