Isotonisina
Isotonisina is a term used in speculative biology and fictional science to describe a hypothetical class of molecules that regulate cellular tonicity to maintain isotonic conditions. The name combines iso- (equal) and tonicity, reflecting its proposed function. There is no established evidence that an actual compound by this name exists in real-world biochemistry.
In the conceptual model, isotonisina would be an amphipathic molecule or polymer capable of reversible hydration.
Potential applications discussed in theoretical contexts include educational demonstrations of osmoregulation, the design of synthetic cells,
In science fiction and speculative biology narratives, isotonisina is sometimes portrayed as enabling long-term tissue viability
