Question

Which of the following is an essential amino acid?

• A. Alanine
• B. Leucine
• C. Glycine
• D. Glutamine

Hint:

Essential amino acids include leucine, isoleucine, valine, phenylalanine, tryptophan, and others. They must be obtained through diet.

Answer 1

The Correct Option is B

An essential amino acid is one that cannot be synthesized by the human body and must be obtained through the diet. Leucine is an essential amino acid, meaning the body cannot produce it, and it must be acquired from food sources. On the other hand, glutamine, glycine, and alanine are non-essential amino acids because the body can synthesize them from other compounds.
