Nuclear magnetic resonance studies of boar seminal plasma. Problems encountered in the identification of small molecules: hypotaurine and carnitine

Methionine‐dependence phenotype of tumors: Metabolite profiling in a melanoma model using L‐[methyl‐13C]methionine and high‐resolution magic angle spinning 1H–13C nuclear magnetic resonance spectroscopy

“…However, there is considerable confusion about chemical shifts of Tau in the literature. Two papers deserved special attention, one reporting the follow-up of L- [3][4][5][6][7][8][9][10][11][12][13] C]Cys metabolism in astrocytes (27) and the other analyzing the chemicophysical properties of hypotaurine (28). These papers attributed the downfield 13 C-upfield 1 H signal of Tau or hypotaurine to the C-1 CH 2 residue.…”
