The reason that essential amino acids are not synthesized by human body.
Answer to Problem 9TE
As essential amino acids are taken from outside food sources, humans do not synthesize these amino acids.
Explanation of Solution
As the human are biological evolved, they have formed some characteristic changes in themselves. The production of essential amino acids was occurred in the early human beings but as the essential amino acids can be taken from outside food source, the human body evolved in such a way that it stopped the production of essential amino acids inside it and totally depends upon the outside eatable sources. The synthesis of these essential amino acids is very difficult biochemically inside the body. Hence its evolution made such changes.
Conclusion:
Therefore, as essential amino acids are taken from outside food sources, humans do not synthesize these amino acids.
