CAS:Pantothenic acid (pantothenate) is a water-soluble vitamin of the B complex. It is an essential nutrient that is necessary for the normal development and maintenance of the human body. Pantothenate is necessary for energy metabolism, as well as synthesis of coenzyme A and acetylcholine. Pantothenate also participates in the synthesis of hemoglobin, blood cells, and steroid hormones. Pantothenate deficiency can lead to dermatitis, insomnia, irritability, fatigue, depression, dizziness, muscle pain or cramps, and hair loss. D-Calcium pantothenate (DCP) is a salt form of pantothenic acid that has been shown to be effective in treating coronary heart disease and oxidative injury. DCP has been used as a model system to study polymerase chain reactions (PCR) in vitro.
