Pantothenic Acid – The Vitamin Found Everywhere In Body Cells
Pantothenic acid is also known as vitamin B5 and is a component of coenzyme A (CoA) which in turn is a component of Acetyl CoA which is part of both energy producing pathways and biosynthetic pathways. The vitamin is formed from pyruvate which is a three component compound that is the result of the glycolytic break down of glucose which is the primary energy source for the brain. The vitamin also begins the citric acid cycle, is also a key building block of fatty acids, and is a precursor of ketone bodies. This vitamin whose name derived from the Greek word pantos which means everywhere can be found throughout all living cells.
