The chemical reactions and pathways resulting in the formation of ergosterol, (22E)-ergosta-5,7,22-trien-3-beta-ol, a sterol found in ergot, yeast and moulds. The chemical reactions and pathways resulting in the formation of steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus; includes de novo formation and steroid interconversion by modification. The chemical reactions and pathways resulting in the formation of phytosteroids, steroids of higher plants differing from animal steroids in having substitutions at C24 and/or a double bond at C22. The chemical reactions and pathways involving phytosteroids, steroids of higher plants differing from animal steroids C1 or C2 residues at C24 and/or a double bond at C22. The chemical reactions and pathways resulting in the formation of sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. The chemical reactions and pathways involving ergosterol, (22E)-ergosta-5,7,22-trien-3-beta-ol, a sterol found in ergot, yeast and moulds. It is the most important of the D provitamins and is converted to vitamin D2 on irradiation with UV light. The chemical reactions and pathways involving sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. Any process that decreases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of ergosterol. Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of ergosterol. Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of ergosterol.
