title: Assignment of overlapping (1)H NMR signals in carp seminal plasma by proton-detected 2D C,H correlation spectroscopy.
abstract: The (1)H NMR spectrum of the perchloric acid extract of carp seminal plasma was heavily congested. It is demonstrated that proton-detected C,H chemical shift correlation spectroscopy (HSQC, HSQC-TOCSY) allows an unequivocal identification of proline, glutamate, taurine, and methionine sulfoxide, although several key proton signals were strongly overlapped.
