<p>Metabolomics analysis of FBS and goat serum.</p>

Column A: putative identities of the metabolites; columns B-E: raw peak intensities for four technical replicates of goat serum; columns F-I: raw peak intensities for four technical replicates of FBS; columns J-Q: Log₂-transformed peak intensities for goat serum (J-M) and FBS (N-Q). The transformation was carried out on peak intensities + 1 to ensure that undetected metabolites (peak intensity = 0) returned a value of 0; column R: Log₂ fold change between goat serum and FBS, calculated by subtracting the mean Log₂ FBS from the mean Log₂ goat serum values.

Column S: <i>t</i>-test result for each Log₂FC, calculated using Metaboanalyst; column T: FDR-adjusted P value (<i>t</i>-test). Abbreviations: GS: goat serum; FBS: foetal bovine serum; Log₂FC: Log₂ fold change; FDR: false discovery rate.</p> <p>(XLSX)</p>
