reaktiomoolien

Reaktiomoolien are modular units used to encode the essential information of chemical reactions for use in computational modeling and reaction-network analysis. Each reaktiomooli captures stoichiometry, kinetic parameters, and descriptive metadata, enabling researchers to assemble complex networks from reusable building blocks. They are data structures rather than physical objects and can be combined, split, or substituted without altering the surrounding network.

The term appears in Finnish-language chemistry and informatics literature and is sometimes used to discuss modular modeling approaches in systems chemistry. Conceptually, reaktiomoolien resemble reaction motifs or templates used in other fields to standardize how reactions are represented and parameterized.

A typical reaktiomooli includes: reactants and products with stoichiometric coefficients; a rate expression or kinetic parameters (e.g., rate law, activation energy); reversibility; temperature, solvent, and catalyst information; metadata such as data source and confidence; and references to related reactions or templates. It may also specify constraints, such as compartmentalization or enzyme catalysis.

Applications include building scalable reaction networks, automating parameter estimation, and supporting simulations in cheminformatics, systems chemistry, and chemical engineering. They facilitate modular design, enable reuse across projects, and support interoperability when paired with standard data formats.

Limitations include reliance on consistent definitions and data standards, potential ambiguity when different groups propose variants, and the need for encoding conventions to ensure compatibility with existing formats like SBML, ChemKin, or JSON-based templates.
