Precursor in the biosynthesis of coenzyme A.

Biochem/physiol Actions

D-Panthenol is the alcohol analogue and biological precursor of D-pantothenic acid. These analogues are precursors in the biosynthesis 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.

Physical properties

Due to the unstable, hygroscopic nature of the free acid, the calcium salt is employed.

High-throughput screening often identifies not only specific, stoichiometrically binding inhibitors but also undesired compounds that unspecifically interfere with the targeted activity by nonstoichiometrically binding, unfolding, and/or inactivating proteins. In this study, the effect of such unwanted inhibitors on several different
