Acids, Bases And Salts

- Let's explore the real life applications of acids, bases and salts

Acid-Base chemistry in stomach

Even though we are scared of acids and their corrosive power, we cannot deny the fact that our stomach produces one of the strongest naturally produced acids.
You may already know how stomach acid helps in the digestion of food.
But you think it's not powerful enough? Now here's a bit of news-the pH of stomach ranges from 1 to 2. So, it's pretty strong! That's why it can break down food in the stomach easily.
But with such a strong acid in the stomach, what keeps it from cutting through our stomach lining?
You can actually thank a simple acid base reaction for protecting you. Watch this video to find out more about how stomach protects itself:
Why doesn't your stomach digest itself?

Amino acids - Acids that build you

We definitely make proteins in our body. But a lot of it comes from the food we eat.
Eggs, cheese, milk and various pulses are delicious protein rich food. We eat them because our bodies need proteins for various activities- for something as simple as making our muscles move.
It should not come as a surprise, but proteins make up almost every other body part- skin, hair, muscles and bones. So, it's a very basic structure found in the human body.

But what is a protein? It's basically a large molecule. It's a molecule made up of hundreds and thousands of smaller units
expand
But did you know that the units are of acids, more specifically amino acids

So, amino acids are smaller molecules, containing C, H, O and sometimes S atoms. There are 22 different amino acids and they can be arranged in different ways to make different proteins.
When we consume anything rich in proteins, our bodies break down the chains into the individual amino acids. And then it remakes them into the protein it needs

So, I like to think of proteins as folded strings with differently coloured beads- each bead signifying an amino acid

DNA and RNA- Acids responsible for heredity.

Do you hear this often: you look like your parents?
I am sure you do on many instances!
Well, did you know it's got a lot to do with acids!
expand
You may ask how!
You are probably aware of the fact that DNA and RNA are responsible for the transfer of traits from your parents to you.
And you would be transferring them to the next generation and so on.
But did you ever get a chance to know what DNA and RNA stand for?
So, Deoxyribonucleic Acid is for DNA. And RNA stands for Ribonucleic Acid.
Yes! Both are acids!!
So the next time someone comments on how you look similar to your parents, remember it's because of the function of these acids!
