As you know BioGrid is a database that contains the information of relations between genes, i.e. network of genes. Now, I was wondering if we have such database for metabolite data. I appreciate if you would help me. Indeed, I want to make a network between metabolites and I do not know any database that I can use.
I hope this will help you:
It's a paper-summary from 2015:

A shorter list of databases:
You are not the first person who was going to create such a database, some people shared their views on the topic:
You can take a look at ipath2 , reactome and consensuspathdb, they should be having metabolic pathways for gene-gene relationships to consequent pathways. Even IPA has it but you need a commercial license for IPA.
