Question

WHY DO WE GET TEARS WHILE CUTTING ONIONS?????????????

Answer 1

Lachrymatory-factor synthase is released into the air when we cut an onion. The synthase enzyme converts the sulfoxides (amino acids) of the onion into sulfenic acid. The unstable sulfenic acid rearranges itself into syn-ropanethial-S-oxide. Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes.
