vitamin B5

vitamin B5 Pantothenic acid, a water-soluble, B vitamin that is widely distributed in nature. Pantothenic acid is virtually ubiquitous. It is present in foods as diverse as poultry, soybeans, yogurt, and sweet potatoes. No naturally occurring disease due to a deficiency of vitamin B5 has been identified, due to the ease of obtaining this vitamin. An experimental deficiency of pantothenic acid has, however, been created by administering an antagonist to pantothenic acid. This experiment produced disease, thereby demonstrating that pantothenic acid is essential to humans.
