Despite their significance, the biosynthetic pathway of withanolides remains poorly understood. It is hypothesized that withanolides are synthesized through the universal sterol pathway, wherein sterol precursors undergo various biochemical modifications such as hydroxylation, oxidation, cyclization, and glycosylation, yielding a diverse array of downstream withanolides and withanosides. Consequently, comprehending the biosynthetic pathway of withanolides is crucial to facilitate advancements in withanolides productivity through metabolic engineering or synthetic biology approaches.
