Which of the following statements regarding the biochemical role and properties of vitamins and coen — Biomolecules Chemistry Question

💡 Solution & Explanation

Coenzymes are essential organic non-protein cofactors often derived from B-vitamins. Vitamin $B_{12}$ (Cyanocobalamin) specifically contains a central cobalt atom. Provitamins (like $\beta$ -carotene) are inactive precursors to vitamins. Water-soluble vitamins (except $B_{12}$) are generally not stored and are rapidly excreted in urine, making statement C incorrect.
