/takɪˈstɛrɒl/

Etymology: < German tachysterin (A. Windaus et al. 1932, in Ann. d. Chem. CCCCXCIX. 188): see tachy- comb. form and sterol n.

Biochemistry.

An oily isomer of ergosterol and lumisterol, C₂₈H₄₃OH, which will form calciferol when irradiated with ultraviolet light.

1954 A. White et al. Princ. Biochem. l. 1053 Of the series of compounds obtained from the irradiation of ergosterol only calciferol (vitamin D₂) possesses antirachitic activity. However, one of the series, tachysterol, may be catalytically reduced to dihydrotachysterol.., which is antirachitic.

1976 H. Campion et al. in B. E. C. Nordin Calcium, Phosphate & Magnesium Metabolism xii. 445 Lythgoe has reported the synthesis of a closely related isomer, tachysterol, by a nonphotochemical pathway.
