Practice question
Question
Deficiency of which of the following amino acids in the diet leads to insufficient synthesis of the vitamin niacin resulting in the disease Pellagra ?
Explanation
This outcome reflects enzyme catalysis and lipid structure, where substrate affinity, transition state stabilization and phospholipid composition govern function. Option B captures this correctly because it reflects catalytic efficiency and membrane organization, consistent with textbook descriptions and experimental observations in biochemistry.
