Summary Introduction
Introduction:
Dietary protein is considered as the most crucial nutrient that is composed of amino acids. Proteins play vital structural and functional role in human body. However, the human body is unable to produce essential amino acids by their own. Animal foods are typically rich in protein content, which additionally have all the required essential amino acids. When amino acids are not being burned up by the cell to produce proteins or synthesize nitrogen-containing compounds, then amino acids are designated as “wasted”.
