Solutasolla

Solutasolla is a hypothetical cell-like compartment used in discussions of solute management and reaction compartmentalization in chemistry and origin-of-life studies. The term appears in theoretical models and some science fiction narratives as a simple, self-contained environment that concentrates dissolved substances to drive chemical transformations. In most proposals, a solutasolla is envisioned as a spherical enclosure with a selectively permeable boundary that allows a chosen set of solutes to diffuse in and out, while retaining higher concentrations of reactants inside. The interior is often imagined to host enzymes or catalytic systems that operate more efficiently at elevated solute concentrations. Structures proposed for solutasolla include lipid-based vesicles (liposomes), polymeric vesicles (polymersomes), or coacervate droplets that resemble phase-separated condensates.

Formation and stability depend on membrane composition, osmotic balance, and energy input. In theoretical treatments, solutasolla models help study how compartmentalization could enhance reaction yields, enable metabolic-like cycles, and support the growth or division of primitive cell-like systems. Critics note that real-world implementation faces challenges such as maintaining stability, selective permeability, and sustainable energy sources, especially over multiple cycles of growth and reproduction.

Solutasolla remains a conceptual tool in education and speculative research rather than a widely realized laboratory construct.
