  1. GO-terms in the Biological Process (BP), Molecular Function (MF) and Cellular Compartment (CC) categories that were significantly enriched (p-value < 10E-7) towards the top of the lists of transcripts ranked according to correlation to each of the quantified metabolites. Enrichment is defined as (b/n)/(B/N), where N is the total number of genes, B is the total number of genes associated with a specific GO term, n is the number of genes in the "target set", b is the number of genes in the "target set" associated with a specific GO term [21]. The p-value threshold corresponds to fdr = 8 metabolites * (877 CC GO-terms*10^-7 + 2416 MF GO-terms*10^-7 + 6307 BP GO-terms*10^-7)/31 significant GO terms = 0.003. There were no significantly enriched GO-terms associated with GPC or PCho
