I am learning metabolomic pathway analysis and new to metabolites analysis. If I would like to use KEGG database to map pathway, I wonder how I extract pathways manually? (using R)
For example, I have three metabolites names: c("Acetoacetic acid", "Beta-Alanine", "Creatine") 1. How to find its KEGG ID? And how to get the pathway list with corresponding compound ID/names? 2. Is there a best practice to standardize metabolites names in order to match KEGG compounds?
