Why do Onions make you cry
The Chemistry Of Onions
Onions contain the chemical syn-Propanethial-S-oxide which stimulates the eyes' lachrymal glands and causes us to release tears. Scientists used to blame the enzyme alliinase for the instability of substances in a cut onion. But recent studies from japan show that lachrymatory-factor synthase is the culprit.

Process
- Lachrymatory-factor synthase is released into air as soon as you cut an onion
- Synthase enzyme converts the sulfoxides (amino acids) of the onion into sulfenic acid.
- The sulfenic acid rearanges itself and becomes syn-ropanethial-S-oxide.
- Syn-ropanethial-S-oxide is released into air and comes in contact withour eyes. Therefore irritating the lachrymal glands in our eyes and causing tears to come out
