Question

What are essential amino acids

Answer 1

The amino acids that are unable by the organisms to produce them are essential amino acids, so they take them in in their diet as supplements. The nine essential amino acids are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine.

Essential amino acids or the indispensable amino acids, cannot be made by the organism. So they have to be derived from food. There are nine essential amino acids. They are lysine, phenylalanine, tryptophan, histidine, isoleucine, leucine, methionine, threonine, and valine.
