Incomplete database does not have pathways on amino acid metabolism, lipid metabolism, ion metabolism, ECM biosynthesis metabolism.

Many of the files from BioModels are not valid, and the curated files don't seem to have would I am looking for. Would you suggest that there are other databases that have files that work or is BioModels pretty much the main one to go to. If it is my best option, then I will look for other models that are curated.

I want to model human cell metabolism cultured in a well. I would like to model carbohydrate metabolism, amino acid metabolism; lipid metabolism (eg cholesterol), minerals metabolism, which I think are the main pathways for cell metabolism.

Would you suggest any models that could be a good fit for my purpose? I don't mind where they come from, as long as they run and I can do things on them like changing concentrations and graphing their extracellular matrix production, which may require gene expression pathways. Thank you so much again if you could help me.
