______________

✔️Onions contain some substances which contain sulphur. Sulphur is an irritant to our nose and eyes. When an onion is cut sulphur compounds are released which irritate the nerve endings in our eyes, make them blink and release tears in order to wash the eye off the irritant.

Answer 2

Answer:

Onions consist of amino acid sulfoxides.

When we cut an onion, millions of onions cells rupture, releasing the amino acid sulfoxides along with some special enzymes.

These special enzymes react with amino acid sulfoxides to form a chemical called Syn-propanethial-S-oxide.

This chemical is volatile, that is, it easily evaporates at normal temperature, forming a gas.

When this gas reaches our eyes, it reacts with the substance that keeps our eyes lubricated and forms mild sulfuric acid.

This sulfuric acid gives us a burning sensation.

Now, in order to wash off this acid, our lacrimal glands produce a disinfecting liquid.

But when our eyes cannot hold any extra amount of disinfecting liquid, it starts to fall down, making us cry.
