Question

Identify the essential amino acids from below:
(A) Valine
(B) Proline
(C) Lysine
(D) Threonine
(E) Tyrosine
Choose the correct answer from the options given below:

• A. (A), (C) and (D) only
• B. (A), (C) and (E) only
• C. (B), (C) and (E) only
• D. (C), (D) and (E) only

Hint:

Essential amino acids are those that the body cannot produce on its own, and must be acquired from food. Examples include Valine, Lysine, and Threonine.

Answer 1

The Correct Option is A

Essential amino acids are those that cannot be synthesized by the human body and must be obtained through the diet. Among the amino acids listed: 
-Valine (A) is an essential amino acid. 
- Proline (B) is a non-essential amino acid, as the body can synthesize it. 
- Lysine (C) is an essential amino acid. 
- Threonine (D) is an essential amino acid. 
- Tyrosine (E) is a non-essential amino acid because it can be synthesized from phenylalanine, which is essential. 
Thus, the essential amino acids are Valine, Lysine, and Threonine, making the correct answer (1).
