Samples were analyzed by reversed-phase HPLC according to the method described by Hollenbach et al., 2020 [24 (link)]. The HPLC system was equipped with a Kinetex EVO C18 column (2.6 μm, 250 × 4.6 mm) from Phenomenex (Aschaffenburg, Germany) with an accompanying guard column (4 × 3.0 mm ID) of the same phase using an Agilent (Waldbronn, Germany)1260 series liquid chromatograph equipped with a quaternary pump, an autosampler and a column oven. Analytes were detected using an evaporative light scattering detector from BÜCHI Labortechnik (Essen, Germany). The retention times were 2.1 min for glucose and 2.7 min for glucose monodecanoate.
