Question

why does tears come out of our eyes while we cut an onion ?​

Answer 1

Answer:

When an onion is sliced or diced, the onion's cells release these compounds into the air. When this occurs, "enzyme" works to alter the amino acids into lachrymator compounds. This form of sulfuric acid irritates the nerves around the eyes making them tear.

Answer 2

Hey mate!!

When an onion is cut, certain (lachrymator) compounds are released causing the nerves around the eyes (lacrimal glands) to become irritated.

These compounds consist of methionine and cystine that are part of the amino acid family. (Protein is made up of several of these amino acids grouped together.)
