Scientific background
Vitamin B5, chemically known as pantothenic acid, is a water-soluble vitamin and a critical component of Coenzyme A (CoA). Derived from the Greek word "pantothen" meaning "from everywhere," it is ubiquitously found in various plant and animal foods. In human metabolism, pantothenic acid is essential for the synthesis of Coenzyme A, a crucial coenzyme involved in over 100 enzymatic reactions. Its primary mechanism of action involves CoA acting as an acyl group carrier, facilitating key metabolic processes such as the oxidation of fatty acids and carbohydrates for energy production via the Krebs cycle. It also plays a vital role in the biosynthesis of fatty acids, cholesterol, steroid hormones, and neurotransmitters like acetylcholine. Due to its widespread presence in the diet, clinical deficiency of pantothenic acid is rare, typically only seen in severe malnutrition or genetic disorders impacting its metabolism. While supplementation is generally not required for healthy individuals, ongoing research explores its potential roles in skin health, wound healing, and support for adrenal function, though further robust clinical evidence is needed for these applications.
