Vitamin B5 – pantothenic acid

to overview Vitamins

Occurrence and structure

Pantothenic acid occurs both in animal and in vegetable products, particularly plentifully in yolk, liver and kidney. In addition it is formed by our intestine bacteria. It is developed from beta Alanin and Pantoinsäure.

Further Vitamin B5 is contained in: Nuts, rice, fruit, vegetables and brewer’s yeast. Its most important function is as a component of coenzyme A, which consists of pantothenic acid, cysteine and ATP. Coenzyme A serves many substrates for activation, as it contains an energy-rich thiol (SH) group. For example, fatty acids are activated (acyl-CoA) or acetate is activated to acetyl-CoA, which is a key substrate of the entire metabolism.

Symptoms of deficiency

They are very rare, since pantothenic acid is very common. If they are present, the fat metabolism, protein synthesis and the nervous system are primarily affected, since the neurotransmitter acetylcholine is produced from acetyl-CoA and choline.
