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 lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. 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 saponins, glycosides of plants in which the aglycan (sapogenin) moiety is a terpene or steroid and the sugar moiety is a glucose, a galactose, a pentose, a methylpentose or an oligosaccharide. Saponins are powerful surfactant agents and membrane active; they are, hence, toxic to animals on injection. The chemical reactions and pathways resulting in the formation of brassinosteroids, any of a group of steroid derivatives that occur at very low concentrations in plant tissues and may have hormone-like effects. The chemical reactions and pathways involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus.
