Question: 1 / 400

Which of the following is not a non-essential amino acid?

Alanine

Lysine

Lysine is classified as an essential amino acid, which means that it cannot be synthesized by the human body and must be obtained from food sources. This is a critical distinction because essential amino acids play a fundamental role in various biological processes, including protein synthesis, tissue repair, and the production of hormones and enzymes.

On the other hand, alanine, glutamine, and serine are all considered non-essential amino acids. The body can produce these amino acids, so they can be synthesized from other compounds within the body, allowing individuals to rely less on dietary sources for their intake. Understanding this classification is important in nutrition and health, as it can influence dietary planning, especially for those who may have specific protein needs based on activity level, health conditions, or dietary restrictions.
