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 indispensable for human health as the body lacks the capacity for their synthesis, necessitating dietary intake. Based on the provided amino acids: - Valine (A) is classified as essential. - Proline (B) is non-essential due to endogenous synthesis. - Lysine (C) is an essential amino acid. - Threonine (D) is an essential amino acid. - Tyrosine (E) is non-essential because it can be synthesized from phenylalanine, an essential amino acid. Consequently, Valine, Lysine, and Threonine are the essential amino acids, indicating (1) as the correct selection.
