Vorläufer für die Biosynthese von Coenzym A

Biochem./physiol. Wirkung

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.

Physikalische Eigenschaften

Aufgrund der instabilen, hygroskopischen Natur der freien Säure, wird das Calciumsalz verwendet.
