 # [Loading Chemical Reaction Network Models from Files](@id model_file_import_export)
-Catalyst stores chemical reaction network (CRN) models in `ReactionSystem` structures. This tutorial describes how to load such `ReactionSystem`s from, and save them to, files. This can be used to save models between Julia sessions, or transfer them from one session to another. Furthermore, to facilitate the computation modelling of CRNs, several standardised file formats have been created to represent CRN models (e.g. [SBML](https://sbml.org/)). This enables CRN models to be shared between different softwares and programming languages. While Catalyst itself does not have the functionality for loading such files, we will here (briefly) introduce a few packages that can load different file types to Catalyst `ReactionSystem`s.

 ## [Saving Catalyst models to, and loading them from, Julia files](@id model_file_import_export_crn_serialization)
 Catalyst provides a `save_reactionsystem` function, enabling the user to save a `ReactionSystem` to a file. Here we demonstrate this by first creating a [simple cross-coupling model](@ref basic_CRN_library_cc):

 ## Lost support for most units
-As part of its v9 update, ModelingToolkit changed how units were handled. This includes using the package [DynamicQuantities.jl](https://github.com/SymbolicML/DynamicQuantities.jl) to manage units (instead of [Uniful.jl](https://github.com/PainterQubits/Unitful.jl), like previously).

 While this should lead to long-term improvements, unfortunately, as part of the process support for most units was removed. Currently, only the main SI units are supported (`s`, `m`, `kg`, `A`, `K`, `mol`, and `cd`). Composite units (e.g. `N = kg/(m^2)`) are no longer supported. Furthermore, prefix units (e.g. `mm = m/1000`) are not supported either. This means that most units relevant to Catalyst (such as `µM`) cannot be used directly. While composite units can still be written out in full and used (e.g. `kg/(m^2)`) this is hardly user-friendly.
