Pantothenic acid is a precursor of coenzyme A (CoA), an important cofactor and acyl group carrier in cells. One of the main functions for CoA is the formation of acetyl-CoA, support for cellular respiration and the metabolism of carbohydrates and fatty acids through the Krebs cycle. Distribution studies indicate that tissues with the highest retention of pantothenic acid are the kidneys, pituitary gland, heart, muscle, liver and adrenal glands. Additionally, pantothenic acid is required for the synthesis of fatty acids and membrane phospholipids, the amino acids leucine, arginine and methionine, and isoprenoid derivatives, including steroid hormones, vitamin A and vitamin D.
Cellular Energy: Pantothenic acid supports cellular energy production by promoting proper metabolism of carbohydrates and fatty acids.
Nutrient Synthesis: Pantothenic acid helps the synthesis of vitamins, amino acids, and fatty acids.
Fatty Acid Metabolism: Pantothenic acid is a precursor of coenzyme A (CoA) which is essential for fatty acid transport and fatty acid metabolism.
