Many vitamins function as coenzymes or coenzyme precursors. For instance, Vitamin B6 (Pyridoxine) is converted into Pyridoxal phosphate, a coenzyme involved in amino acid metabolism. Similarly, Vitamin B2 (Riboflavin) is a precursor to FAD (Flavin adenine dinucleotide) and FMN (Flavin mononucleotide), which are essential for redox reactions in various metabolic pathways.
