What vitamin is needed by nearly all amino acids for metabolism?Multiple choice question.Vitamin CRiboflavinVitamin B-6

Break Down the Problem

1. Identify the amino acids and their metabolic needs.
2. Determine which vitamin is essential for the metabolism of nearly all amino acids from the given options.

Relevant Concepts

1. Amino acid metabolism typically involves the processes of transamination and deamination, which require certain coenzymes derived from vitamins.
2. The options provided are:
   • Vitamin C
   • Riboflavin (Vitamin B2)
   • Vitamin B-6 (Pyridoxine)

Analysis and Detail

1. Vitamin C: Primarily known for its antioxidant properties and role in collagen synthesis; not directly involved in amino acid metabolism.
2. Riboflavin: Important for energy production and the metabolism of fats, drugs, and steroids, but not specifically tied to amino acid metabolism.
3. Vitamin B-6 (Pyridoxine): Crucial for amino acid metabolism, particularly because it acts as a coenzyme in transamination reactions, which are essential for the synthesis and breakdown of amino acids.

Verify and Summarize

• After analyzing each vitamin's role, it is clear that Vitamin B-6 is the most vital for amino acid metabolism due to its role as a coenzyme in transamination reactions.

Final Answer

Vitamin B-6 is needed by nearly all amino acids for metabolism.
