Vitamin D4

Vitamin D4 is a vitamin produced in fungi from the UV irradiation of 22,23-dihydroergosterol (Provitamin D4). It is produced by several mushroom species including A. bisporus, F. velutipes, G. frondose, and C. cibarius and in S. cerevisiae. Vitamin D4 is 60% as active as vitamin D3 (Cay-11792) at healing rickets in rats.Formal Name: (1S,3Z)-4-methylene-3-[(2E)-2-[(1R,3aS,7aR)-octahydro-7a-methyl-1-[(1R,4S)-1,4,5-trimethylhexyl]-4H-inden-4-ylidene]ethylidene]-cyclohexanol.
