A Review on Amino Acids
Abstract: Protein is made up of amino acids, which are the building blocks of the molecule. Only 20 amino acids are involved in protein synthesis, even though more than 300 amino acids have been identified. In nature, all twenty amino acids did not appear at the same time. Rather, some of them appeared first, while others were later incorporated into the genetic code. It is vital to include them in one's …
