2	30	41	1.367	Bile Acid metabolism, Amino Acid and Purine metabolism
3	22	23	2.09	Amino Acid, Nucleotide metabolism
4	15	21	2.8	Plasmalogens, Lyso-plasmalogens, Phosphatidylcholines
5	13	18	2.77	Fatty Acid metabolism (Acyl carnitines, Acyl Amino Acids)
6	13	12	1.85	Carbohydrate, Amino Acid, Nucleotide metabolism
7	6	6	2	Vitamin A metabolism, Amino Acid metabolism
8	6	6	2	Benzoate metabolism, Amino acid metabolism

¹Average degree represents the average number of connections each node (metabolite) makes within the module and indicates the network/module density.
