Vitamin B5 is essential for coenzyme A synthesis and energy metabolism.
Vitamin B5, also known as pantothenic acid, is a water-soluble B vitamin essential for the synthesis of coenzyme A (CoA), which is critical for energy metabolism and the synthesis of various molecules including fats, cholesterol, and hormones.
Pantothenic acid serves as a precursor to coenzyme A (CoA), one of the most important molecules in metabolism. CoA is involved in the activation and transfer of acyl groups in hundreds of enzymatic reactions, particularly in the breakdown of fatty acids and carbohydrates through the citric acid cycle. Beyond energy metabolism, CoA is necessary for the synthesis of fatty acids, cholesterol, steroid hormones, and the neurotransmitter acetylcholine. Pantothenic acid also plays a role in the synthesis of hemoglobin and in the maintenance of healthy skin and hair. Because B5 is widely distributed in foods and the body maintains adequate stores, deficiency is rare in humans. The vitamin is heat-labile and can be lost during food processing and cooking.
Essential precursor to coenzyme A, supporting energy metabolism and the synthesis of lipids, hormones, and neurotransmitters.
Daily requirements are 5 mg for adults; ensure intake through varied whole foods, as pantothenic acid is widely available but can be lost in processing. Include at least one B5-rich source daily.
Vitamin B5 is fundamental for the synthesis of coenzyme A, making it essential for nearly all metabolic pathways.
