Application

D-Pantothenic acid hemicalcium salt has been used as a supplement in complete media to culture Aspergillus-nidulans.
Precursor in the biosynthesis of coenzyme A.

Biochem/physiol Actions

D-Panthenol is the alcohol analog and biological precursor of D-pantothenic acid. These analogs are precursors in the biosynthesis of the phosphopantetheine moiety of coenzyme A. D-Panthenol and D-Pantothenic acid are used in a variety of skin protection products. D-pantothenic acid may have a role in controlling keratinocyte proliferation and differentiation. D-Panthenol may be used for studies of skin protection emulsions from UV irradiation and as a humectant. D-pantothenic acid is crucial for normal epithelial function. It facilitates wound healing process.

General description

D-Pantothenic acid hemicalcium salt, also referred as calcium D-pantothenate, is a water soluble B complex vitamin. It is present in a variety of foods.
Due to the unstable, hygroscopic nature of the free acid, the calcium salt is employed.
