The metabolite profile of the sphingolipid metabolism. a The schematic diagram of the pathway. Yellow box indicates metabolite not measured in the metabolomic discovery, green box indicates metabolite measured but did not change in response to peptide treatment, blue box indicates metabolite that was down-regulated compared to control. b Box plots of selected biochemicals. Values are normalized raw area counts rescaled to set the median equal to 1. * Indicates p < .05 compared to control
