Question

Why our eye bring tears while cutting onions?

Answer 1

Answer:

The synthase enzyme converts the amino acids sulfoxides 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. The lachrymal glands become irritated and produces the tears

Answer 2

$\huge\bold\red{gud night}$

Onions produce the chemical irritant known as syn-propanethial-S-oxide.

It stimulates the eyes' lachrymal glands so they release tears.

Scientists used to blame the enzyme allinase for the instability of substances in a cut onion.

The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid.
