folosine

Folosine is a term that appears primarily in science fiction and speculative chemistry as the designation for a fictional chemical compound. It is not a real substance recognized by major chemical databases, and there is no universally accepted structure, formula, or set of properties associated with it. Because folosine lacks a canonical identity, its definition varies by author and narrative.

In many works, folosine serves as a flexible plot device rather than a real chemical with fixed characteristics. Writers may assign it any combination of properties—such as being a high-energy storage molecule, a photoresponsive material, a catalyst, or a signaling agent—depending on the needs of the story. Its fictional nature allows creators to explore themes of resource scarcity, regulation, safety, and biosecurity without committing to a real compound.

In worldbuilding, folosine can function as a speculative technology enabler: a synthetic feedstock, an obscure mineral extract, or a biologically produced metabolite with unusual effects. Because its identity is not standardized, authors can calibrate its plausibility by defining a plausible synthesis pathway, production scale, industrial processing, and environmental impact within the created universe.

If you are developing a work that includes folosine, it is helpful to establish a clear in-universe definition: its class, method of production, stability, and regulatory status. This consistency helps readers suspend disbelief and strengthens the narrative.
