For protein-ligand docking calculations one can use free databases such as ZINC (http://zinc.docking.org). But I need to find databases of compounds that are present in human food. In zinc I can see there is the "natural products" subset, but I would like to focus just on some "food" subset. Are there other databases available for such compounds?
PS: I mean databases where one can download the compounds in any of the standar formats (mol2, sdf, smiles, etc)
This looks good but I could only find around 127 compounds
My guess is they are waiting for funding in sequence after DrugBank and HMDB. As you can see below your question cannot be answered from any current database even the FDA (additives yes but not food chemistry). This is a massive gap (considering eating is our biggest chemical exposure bar none) that I hope FOODB will plug soon. Given the size of the global food/nutrition industry you'd of thought they might offer to help, but there are also reasons why they might not. I guess some of those 1000 to 50000 substances in food will turn out not to be so good for us as we thought. No harm in asking Nestle if they have made their own database though.
