Ergosterola esterolen saileko alkohola da(C₂₈H₄₄O).

Zekale-ainotik (Claviceps purpurea) lortzen da batez ere, baina garagar-legamiatik ere ateratzen da gaur egun. Animalia- eta landare-ehun batzuetan ere aurkitzen da. Mutur batean daukan hidroxilo taldeari esker molekula anfipatikoa da.

Erradiazio ultramorea jasotzen duenean, kaltziferol edo D₂ bitamina bilakatzen da. Giza gorputzean, kaltzioa hezurretan eta hortzetan katalizatzea da haren eginkizun nagusia.
