DETAILS

Description (简体中文)

Application
生物合成辅酶 A 的前体。
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
由于游离酸具有不稳定性和吸湿性，因此采用钙盐的形式。
