Sample Preparation:

Sampleprep ID:	SP001733
Sampleprep Summary:	Metabolites were extracted according to the methodology described in Fiehn 2017 Curr Protoc Mol Biol. ; 114: 30.4.1–30.4.32. doi:10.1002/0471142727.mb3004s114. Briefly, 1 mL 3:3:2 acetonitrile:isopropanol:water was added to ~4 mg cecal contents/feces. Samples were homogenized and then shaken at 4 C for 6 min prior to centrifugation at 14,000 x g for 2 minutes. An aliquot of 475 µl supernatant was taken for subsequent analysis, evaporated, cleaned with acetonitrile and water (1:1), and fully evaporated to dryness. 10 µl MeOH and 91 µl MSTFA were added to all samples for derivatization.
