Final answer:
The statement is false. Essential amino acids can't be synthesized by the body from other amino acids, they must be ingested through diet. These amino acids are necessary for protein construction in the body.
Step-by-step explanation:
The statement is False. Essential amino acids are indeed physiologically crucial, but they cannot be synthesized by the body from modifying other nonessential amino acids. Instead, they must be obtained from the diet. Similarly, some nutrients, named essential nutrients, must also be consumed from food, as the body cannot produce them.
These essential amino acids are required for the construction of proteins within the body, and they reside in the amino acid pool within cells. If an essential amino acid is not available in sufficient quantities in this pool, the synthesis of proteins containing it can slow or even cease. Examples of such essential amino acids in humans include isoleucine, leucine, and cysteine.
