1H-NMR analysis has been described in detail previously [31 (link)]. In short, spectra were recorded at 800 MHz with a Bruker Advance III HD spectrometer with a 3-mm TCI cryoprobe. NMR data were recoded using the Bruker pulse sequence “zgespe”. A total of 128 scans were collected into 64 k data points. Data processing was performed with TopSpin 3.2p16 (Bruker BioSpin) and MatLab (MathWorks Inc., Natick, MA, USA), using TSP-d4 for referencing. In total 237 peaks were manually aligned and integrated peak-by-peak, and these variables represent ∼70 metabolites. A variable could also reflect more than one metabolite. Only variables of interest were identified.
For annotation Chenomx NMR suite 8.31 (Chenomx Inc., Edmonton, AB, Canada), the Human Metabolome Database [37 (link)] and an in-house implementation of the statistical total correlation spectroscopy (STOCSY) routine [38 (link)] were used.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
