Why the onion makes us cry is one of the great questions of gastronomy, and the culprits are sulfur compounds that are released and transformed by cutting the onion

However, among all the qualities of this edible bulb, there is one that is somewhat uncomfortable and is precisely the eye irritation that causes us when we cut it.
One of the characteristics of the onion is the presence of sulphoxide amino acids in its cellular liquids. When cutting the onion, the cells of this are broken releasing these sulfur compounds. Another substance released when cutting the onion, is an enzyme called alinasa, which converts the sulphoxide amino acids into sulfenic acids, one of which, after another reaction, finally gives rise to the thiopropanal sulfoxide, which is the gaseous substance that triggers the itch, irritation and tearing when it reaches our eyes.
How to prevent the onion from making us cry?
Any of the methods that reduce tearing when cutting onions are based on inactivating or reducing some of the substances involved in the production of thiopanal sulphoxide. For example: heating the onion before cutting would inactivate the enzyme alinasa, which would not form the substance that causes ocular irritation. Likewise, cooling the onion before cutting it would slow down the reactions responsible for the formation of the lachrymatory compound. Finally, wet the onion or cut it in a ventilated place would save us a few tears by diluting or reducing the concentration of the substance that triggers eye irritation
Whenever I'm cooking, I always love to call on my kid sister to come cut onions for me. Lol, this is probably because I hate crying.
The reason we produce tears when we cut onions is because of the chemical called "Syn-propanethial-S-oxide" which is found in the onions.
The lachrymal glands in our eyes gets irritated by this chemical and hence reacts against it by producing the tears.

They convert raw sulfur into Associate in Nursing aminoalkanoic acid referred to as sulfoxide. Sulfoxide has the characteristic of reacting with the atmosphere to make gas. Slicing onion means that you in fact cut the individual and microscopic onion cells. after you cut the onion, sulfoxide reacts to make a rotating gas referred to as syn-propanethial-s-oxide. Receptors in your eyes acknowledge foreign gas, and communicate together with your brain that causes tears to flow to assist defend your eyes from these compounds.
The gas compound is merely discharged after you cut the onion. within the change of state method, all of the gas compounds area unit lost. once the onion is heated, the molecule that forms the gas offers a delicious aroma to the cookery and offers flavor to the dish.

This works as such..... The lachrymatory factor is released into the air when we cut onions. The amino acids sulfoxides is convertes into sulferic acid by the enzyme which in turn rearranges itself into syn-propanethiel oxide.
The oxide gets into the air and in contact with our eyes which irritatethe lachrymal gland producing tears.

Lol. I'm just kidding
