Which vitamins form coenzymes that enable specific enzymes to regulate many life sustaining chemical reactions?

Vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin) serve as precursors to essential coenzymes. These coenzymes play crucial roles in various metabolic pathways, facilitating reactions such as energy production, synthesis of neurotransmitters, and DNA replication. Their involvement is vital for maintaining overall health and supporting numerous biochemical processes that sustain life.
