Previtamin D2
Vitamin D2 precursor
Previtamin D2 is a precursor to Vitamin D2 (ergocalciferol) that results from the photoisomerization of ergosterol, a compound present in fungi and certain plants. When exposed to ultraviolet (UV) light, ergosterol is converted to previtamin D2, which subsequently undergoes rapid isomerization to form vitamin D2. This compound is essential for studies involving vitamin D metabolism, cellular signaling, and related therapeutic applications.
