Description
Pantothenic Acid, commonly known as Vitamin B5, is a water-soluble vitamin belonging to the B-complex group. It is an essential micronutrient required for the synthesis of coenzyme A (CoA) and acyl carrier protein (ACP), two indispensable cofactors involved in numerous metabolic pathways. Pantothenic Acid plays a fundamental role in carbohydrate, lipid, and protein metabolism by facilitating the transfer of acyl groups during biochemical reactions. It is therefore crucial for cellular energy production, fatty acid synthesis and oxidation, cholesterol biosynthesis, steroid hormone production, neurotransmitter synthesis, and normal physiological growth.
The name "pantothenic" is derived from the Greek word pantothen, meaning "from everywhere," reflecting the vitamin's widespread occurrence in both plant and animal foods. Because of its ubiquitous distribution in nature, severe dietary deficiency is relatively uncommon. Nevertheless, adequate intake is essential for maintaining healthy skin, nervous system function, immune responses, wound healing, and normal cellular metabolism.
Pantothenic Acid is extensively utilized in pharmaceutical formulations, dietary supplements, cosmetics, dermatological products, animal nutrition, and food fortification. In cosmetic applications, it is often incorporated as D-panthenol (provitamin B5), which is readily converted to Pantothenic Acid after absorption and is recognized for its moisturizing, soothing, and skin-repairing properties.
CAS Number

Synonyms
Physical Properties
Pantothenic Acid is generally obtained as a white to pale yellow crystalline powder or hygroscopic solid. It possesses excellent water solubility, making it readily absorbed and distributed within biological systems. The compound is odorless or nearly odorless and exhibits a slightly bitter taste.
Typical characteristics include:
Because of its hydrophilic nature, Pantothenic Acid is rapidly dissolved in aqueous pharmaceutical and nutritional formulations.
Chemical Properties
Pantothenic Acid contains both hydroxyl and carboxylic acid functional groups, enabling participation in numerous enzymatic reactions. It is chemically stable under mildly acidic conditions but becomes increasingly susceptible to degradation under strongly acidic, strongly alkaline, or elevated temperature environments.
The vitamin readily forms salts such as calcium pantothenate, which possess superior stability and are therefore preferred in dietary supplements and food fortification.
Chemically, Pantothenic Acid exhibits:
Manufacturing Process
Commercial Pantothenic Acid is produced through controlled chemical synthesis or microbial fermentation, followed by purification and crystallization.
Typical manufacturing stages include:
Calcium pantothenate is frequently manufactured because of its superior storage stability compared with the free acid.
Mechanism of Action
Pantothenic Acid functions primarily through its conversion into Coenzyme A (CoA), one of the most important cofactors in cellular metabolism.
Within cells, Pantothenic Acid undergoes phosphorylation and several enzymatic reactions to produce Coenzyme A.
CoA subsequently participates in:
Without adequate Pantothenic Acid, efficient cellular energy production cannot occur.
