When Proteins Come Together, Magic Happens!

When good things come together, magic happens! That’s exactly the case with proteins too, when they come together inside your body magic happens. By now we know that proteins are essential for muscle growth, tissue repair and transport of nutrients but what we don’t know is how exactly all of this happens.

So lets learn how does this magic unfolds!!!
Whenever we eat food, our body breaks down the proteins present in our diet to produce amino acids. These amino acids are subsequently used for the production of other Proteins like enzymes, hormones, antibodies and neurotransmitters, all of which are required by our body to function properly. Which explains A diet that doesn’t have enough amounts of proteins hampers the growth and maintenance of our body.

Structure of Proteins

sc_011 All proteins are made up of amino acids. Think of amino acids as train cars that make up an entire train called a protein. Proteins are formed by amino acids, which are produced based on the genetic information in a cell. Then, the amino acids that are created in the cell are linked together in a certain order. Each protein is made up of a unique number and order of amino acids. The protein that is created has a specific job to do or a specific tissue (such as muscle tissue) to create.There are about 20 amino acids known including proline, valine, tyrosine, lysine, glutamine and many more.

The Concept of Folding

sc_02 Just knowing the amino-acid sequence is not enough to know about the functionality of a particular protein or how it does its job. In order to perform its function (anti-bodies, enzymes etc) protein must assemble itself to take a particular shape, a procedure that is known as folding. Thus proteins are extremely intelligent machines, one which assembles itself together before it does a certain job. Out of a million ways possible to fold, protein chooses one in a matter of micro-seconds; how it does the same has been a subject of mystery for many years.

Why is shape important?

The particular shape that a protein takes specifies its functionality. For example, a protein that breaks down glucose so the cell can use the energy stored in the sugar will have a shape that recognizes the glucose and binds to it (like a lock and key).
