Simultaneous quantification of straight-chain and branched-chain short chain fatty acids by gas chromatography mass spectrometry. [PDF]

open access: yesJ Chromatogr B Analyt Technol Biomed Life Sci, 2018
Biomedical research in areas such as metabolic disorders, neuromodulatory, and immunomodulatory conditions involves lipid metabolism and demands a reliable and inexpensive method for quantification of short chain fatty acids (SCFAs). We report a GC-MS method for analysis of all straight-chain and branched-chain SCFAs using pentafluorobenzyl bromide ...
