With the help of 3D Animation, why not let's understand the science behind the fact that your eyes water while cutting onions. That is, Why do onions make you cry? To understand the science behind Onions, first, we'll have to grasp two small concepts. In general, when we sow onion seedlings into the ground, it looks something like this. And, after a few months, when we pull out the fully grown onion from the ground, it looks something like this.
In this journey of a few months of becoming young from an innocent, apart from absorbing nutrients from the ground, onion also absorbs one non-metallic chemical element which gave birth to this meme. And, that element is sulfur. And, with the passage of time, this sulfur inside the onion is turned into Amino Acid Sulfoxides. Wait Wait Wait Wait Wait, Professor, we're not having fun, remove such complex wordings and talk about something in daily lives. All right. Definitely, you must have noticed there is a little oily substance on the inner surface of the onion when it is cut. This is the Oily Substance that gives Onion its special flavor. And this is the same Oily Substance within which a class of molecules is found, which is – Amino Acid Sulfoxides. I repeat, remember, from First Concept we have learned about Amino Acid Sulfoxides. As soon as the onion came in your hand from the ground, as soon as you cut the onion, what you saw in the real world is – this knife cut this onion.
But if seen at the microscopic level, this knife cut the Onion Cells. An enzyme is found inside the cells of the onion which is called: Lachrymatory-factor synthase. As soon as the knife cuts the Onion Cell, this Lachrymatory Factor Synthase enzyme is released into the air. Now if I summarize these two concepts, from the first concept, we understood that this Oily Substance is placed on the inner surface of the Onion, which is Amino Acids Sulfoxides and from the second concept we understood that due to the cutting of cells, Lachrymatory-factor synthase enzyme is right here in the air. The real game begins here. Now, this Lachrymatory-factor synthase enzyme will react with Amino Acids Sulfoxides to convert it into Sulfenic Acid. This Sulfenic Acid is highly unstable and rearranges itself into a chemical that no one can pronounce. And, that chemical is Syn-propanethial-S-oxide. This Syn-propanethial-S-oxide is the root cause of all the problems and it is only Syn-propanethial-S-oxide that comes flying in our eyes, due to which we get tears while cutting Onions.
Let's understand how? Going back to school life, let's remind ourselves of The Eye Anatomy. This is the lens of our eyes, which is a convex lens and changes its focal length with the help of these Ciliary Muscles. This dark muscular structure on the outside is called Iris. And to control how much light should enter our eyes, we have a Pupil. This Cornea is what covers the Iris. And, this Cornea is the outermost part of our eye. What surprises me is that maximum people don't know that the tears that come from our eyes are of a total of three types. The first type is emotional tears. The tears that come out of our eyes when we're too happy or too sad is called emotional tears. The second type is reflex tears. Whenever a straw, an irritant or anything that can damage our eyes, enter our eyes, tears that come from our eyes to wash out that thing are called reflex tears.
And, the third type is Basal Tears. You must have definitely noticed that our eyes are always slightly wet or moist. These tears which remain in our eyes 24/7 are called Basal Tears. The most important role of these Basal Tears is to protect your eyes from dust, dirt, and other harmful microparticles. Now that we're talking about protection, let me tell you, whenever you access any website while using the internet on your Smartphone or Laptop by connecting with Weak Password Wifi or Public Wifi, then request to access that website Goes to your ISP i.e. your Internet Service Provider. Not only the website access request but your IP address and other data are also transferred. The problem is, it is not difficult for a professional hacker to track your location, online identity, and even your bank account details when you're shopping on web pages without HTTPS Padlock if they know your IP address. But the good news is that if you use NordVPN, then NordVPN will secure your data by creating a tunnel around it and connect it to a server.
Now this server will access the internet on your behalf. And this hacker will not be able to steal your data easily because of this tunnel or simply because of this encryption. The best part is – it is in your hands to connect with the server of your choice by opting from 5400+ servers of NordVPN in a total of 59 different countries. Anyways, now as soon as this chemical called Syn-propanethial-S-oxide comes in contact with these Basal Tears and cornea, with the help of these Ciliary Nerves, our brain will know that there is definitely something lofty.
Our brain will immediately order lachrymal glands to release tears to wash out this chemical. These Lacrimal Glands which are located just above our eyes will immediately release tears from these ducts and this Syn-propanethial-S-oxide chemical will be completely washed out. If I sum up this whole topic in one line, it would not be wrong to say that we have tears while cutting onions only to save our eyes from the chemicals coming out of them. Scientists believe that these chemicals are inside the onion to protect themselves from pests and herbivores. If the matter went on to safety, Onion arranged for itself, similarly, it is highly important that you also make your own arrangements to protect yourself from internet frauds.
