This vitamin is very common in food, so vitamin B5 nutritional deficiencies are exceptional and their symptoms are general in character.
Lipman’s discovery of pantothenic acid – composed of a pivotal molecule for the functioning of the cell’s energy production (coenzyme A) – was rewarded with the Nobel Prize for Chemistry in 1953, which underlines the importance of this vitamin.
Pantothenic acid enters the composition of coenzyme A, which is involved in almost every metabolism (carbohydrates, lipids, proteins) to produce energy for the cell.
Associated with other group B vitamins (niacin, choline and inositol) and histidine, a particular amino acid, pantothenic acid plays a very effective role in skin protection. It promotes the synthesis of skin lipids, especially ceramides, and helps limit skin dehydration.
The substance’s name comes from the Greek pantos, which means “found everywhere.” The main sources of vitamin B5 are meat, eggs and dairy products.
