$\huge\mathfrak\orange{Hello,}$

$\huge\underline{Answer:}$

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.
