What is the chemical compound that causes eye irritation in onion?
Wiki User
∙ 15y ago
As onions are sliced, cells are broken, allowing enzymes called alliinases to break down amino acid sulphoxides and generate sulphenic acids. Sulphenic acids are unstable and spontaneously rearrange into a volatile gas called syn-propanethial-S-oxide. The gas diffuses through the air and eventually reaches the eye, where it binds to sensory neurons, creating a stinging sensation. Tear glands produce tears to dilute and flush out the irritant.
