What elastin actually is (without the biochemistry headache)? | |
Elastin starts life as tropoelastin, a soluble protein made by cells like fibroblasts (in skin) and smooth muscle cells (in blood vessels). Once secreted, tropoelastin molecules assemble into long fibers and get “riveted” together by special cross-links—think of them like tiny molecular bungee cords. Two of these cross-links, desmosine and isodesmosine, are unique to elastin and give the fibers their signature recoil. The result is a tough, rubbery network that can stretch to several times its length and still return to shape. This elasticity isn’t just for show. Your aorta needs to expand and contract billions of times across a lifetime. Your lungs must unfurl like parachutes with every breath. Your skin has to move through smiles, frowns, and naps on the couch—ideally without creasing permanently. Elastin is the quiet MVP behind all that flex. https://bodykitchen.com/products/pro-elastin ![]() | |
