Vitamin D: The Biotechnology of Ergosteroly for the proper metabolism of minerals and bone formation, in mammals and birds. Biotechnologically speaking, however, one usually refers to the provitamin, ergosterol (.) the main sterol in yeasts and mycelial fungi. The provitamin may be converted to the proper vitamin (D.) which undergoes furthe
