What is the function of arginine?

• A. Arginine is a semi-essential amino acid that has demonstrated importance in immune function and wound healing
• B. Arginine is the primary energy source for muscle
• C. Arginine is a major structural component of collagen
• D. Arginine acts as a vitamin

Answer: (A)

Arginine is a conditionally essential amino acid, meaning most people synthesize enough under normal conditions, but during stress, illness, or rapid growth the body's demand can exceed production. Its importance in immune function and wound healing comes from several roles: as a substrate for nitric oxide production, it helps support immune cell activity and blood flow to healing tissues; and it feeds into pathways that produce precursors for collagen and other repair processes needed for wound repair. It is not the primary energy source for muscle, nor a major structural component of collagen, and it is not a vitamin.
