Amino acids and proteins

Amino acids are the basic building blocks of all proteins. The human body requires at least 20 amino acids to produce different proteins, but the human body can only produce 10 of them, the other are found in our daily food income (healthy diet only).
The protein production starts at the nucleus of each human cell. And they serve the cell by executing a vast physical or chemical tasks. All of these tasks are determined by our own DNA and the way that a protein envelopes itself.
