Vitamin B5

Vitamin B5, also known as pantothenic acid, is essential to all forms of life (1). Its name originates from the Greek word ‘pantos’, meaning ‘everywhere’, as it occurs widespread in foods of plant and animal origin and is found throughout all living cells. Pantothenic acid is a water-soluble vitamin and a precursor for the biosynthesis of  ‘coenzyme A’ (CoA), an essential cofactor in numerous biochemical reactions that sustain life (2).
