Seven selected metabolites that showed diurnal rhythms in normalized concentration in all 3 participants. a. Cortisol, b. bilirubin (Z,Z), c. mannitol/sorbitol, d. dopamine sulphate (2), e. trigonelline (N'-methylnicotinate), f. 1,2-dilinoleoyl-GPC (18:2/18:2), g. 2,3-dihydroxyisovalerate. The x-axis is based on the scale of the DLMO time. The y-axis presents the normalized value of metabolite concentration.
