Why Do Onions Make You Cry?
The most of
an onion consists of water. Onion has also vitamins and sugar compounds. There
are also some compounds in the onions which contain Sulfur. The Sulfur is the
natural component of many smelly substances. Due to the Sulfur, onions repel
the creatures who are eating them. Some other plants repel the creatures in
different ways. Some plants have thorns and some plants have stinging leaves.
These thorns and stinging leaves are made of some special cells. These special
cells make the leaves hard to chew.
Now, we come
to the main point. In the onions, there is a Sulfur compound which is known as
propyl sulfoxide. When you cut an onion into pieces, this compound escape into
the air. When propyl sulfoxide reacts with water vapour in the air or moisture
around your eyes, as a result of this reaction, it is converted into Sulfuric
acid. The Sulfuric acid has a strong smell and it also creates irritation in
your eyes. To overcome this irritation, you will have to wash it out from your
eyes. That’s why tears come into our eyes to wash it out from the eyes.
