what chemical mimics connective tissue disruption in the aorta seen in patients with Marfan syndrome

Beta-aminopropionitrile (a chemical found in certain kinds of ☆sweet peas) causes inhibition of lysyl oxidase, an enzyme responsible for cross-linking elastin fibers and collagen fibers.
Ingestion of this compound can cause connective tissue disruption in the aorta that mimics the myxomatous degeneration seen in patients with Marfan syndrome.
