What is Protein?
Protein is a biomolecule that is a key component for our body. There are more than 10,000 different kinds of proteins found in your body. Each one of them has its own purpose and function. Protein is formed from various amino acids that are linked together. One of the main polymers of protein is polypeptide. Protein can transport molecules, repair cells, help your growth, etc.
Monomers and Polymers
A monomer is the basic building block in the human body. In order to create something, several monomers have to link together. Once they link together, they form something called a polymer. A polymer is the product of the chain of monomers. Several polymers make up another thing, and so on and so forth.
Think of this in another way. Suppose a monomer is one cubicle. If several cubicles join together, it creates an office. The office in this case would be a polymer.
If you break down protein, you would find amino acids. That's right! An amino acid is a monomer to the polymer protein. A protein consists of at least 20 amino acids. There are 8 essential amino acids and 12 non-essential acids. You might be thinking, "Why are they important if they are called non-essential?". All the amino acids are important in your body. However, there are amino acids labeled "essentials" only because your body cannot generate those acids. The non-essential are ones that your body creates non-stop. In your cells, the organelle, Ribosome, is in charge of working with amino acids and protein.
Structure and Function
As you can clearly see above, those are the two main types of protein. Fibrous protein is usually found in our muscles and is used for strength and support of the body. However, on the other hand, Globular protein is usually found in your cells and in your bloodstream. It is used to transport things throughout your body.
