Which list contains all essential amino acids for humans?

1. Alanine, Serine, Tyrosine

2. Lysine, Tryptophan, Methionine, Valine, Phenylalanine, Leucine, Isoleucine, Threonine

3. Glutamine, Glycine, Proline

4. Selenium, Taurine, Asparagine

The correct answer is: Lysine, Tryptophan, Methionine, Valine, Phenylalanine, Leucine, Isoleucine, Threonine

The selected answer is correct because it includes all the essential amino acids that humans must obtain through their diet. Essential amino acids are those that the human body cannot synthesize on its own and therefore need to be consumed from food sources. The essential amino acids for humans are lysine, tryptophan, methionine, valine, phenylalanine, leucine, isoleucine, and threonine. These amino acids play crucial roles in protein synthesis, hormone production, and various metabolic processes. The other options do not contain the complete list of essential amino acids. The first option lists non-essential amino acids that the body can produce. The third option focuses on amino acids that also are not essential, while the last option combines amino acids with a focus on minerals, which do not fall into the category of amino acids at all. Therefore, the correct choice provides a holistic view of the essential amino acids necessary for human health.
