Which of the following groups represents an essential amino acid?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Histidine, isoleucine, leucine, lysine.
- Essential amino acids cannot be synthesized by the human body and therefore must be obtained through the diet. They are crucial for supporting normal growth in children and maintaining proper nitrogen balance in adults.
- Nine amino acids are considered essential because the human body (and other mammals) cannot make them on its own. These are:
- Histidine
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
