Steroid pathway definition imported from the 2026-05-17 portable BLAST/HMM package.

Representative Steroid Reaction Route
Squalene to phytosterols and brassinosteroid branch. The steroid route starts from triterpenoid precursors, proceeds through squalene, 2,3-oxidosqualene, and cycloartenol, and then branches toward phytosterols and brassinosteroids; long branches are shown as curated modules.
