Which of the following is not an essential amino acid?

Question

BlackTom AI · Accepted Answer

To approach this question, I will evaluate each amino acid listed in terms of essentiality for adults.
Option 1: valine. Valine is an essential amino acid, meaning the human body cannot synthesize it and it must be obtained from the diet. Therefore, this choice is not the correct answer to the prompt asking which is not essential.
Option 2: glycine. Glycine is classified as a non-essential (also called dispensable) amino acid because the body can synthesize it on its own and it does not need to be obtained exclusively from the diet under normal conditions. This is the correct identification for a non-essential amino acid.
Option 3: tryptophan. Tryptophan is an essential amino acid; humans must include dietary tryptophan to meet physiological needs. As such, it is not the amino acid that is not essential.
Option 4: phenylalanine. Phenylalanine is essential; the body requires it from the diet and cannot produce adequate amounts endogenously. Hence, this is also not the non-essential candidate.

In summary, valine, tryptophan, and phenylalanine are all essential amino acids, whereas glycine is non-essential, aligning with the provided correct answer.
