Metabolite label to KEGG Id

Question

[ymj]

Hi!

I have a list of metabolite labels with associated values (metabolite A has been found in sample 1), as follows: metabolite_label value Total_C 4.605948787 non_HDL_C 3.598204496 Remnant_C 1.571938945 VLDL_C 0.808513241 Clinical_LDL_C 2.868314163

I want to use the Omu R package to do some metabolomics visualizations, but for that I need each time the Kegg ID. Does anyone knows how to find out? Or are there any other packages that I can use , without the need for Kegg identifiers? I found some questions on Biostars related to the question I have, but did not find a good practical anwer which I can use (or at least I was not able to).

Thank you in advance!
