FIGURE 2.

Assignment of EGCg. a, chemical structure of EGCg. The benzenediol is labeled as ring A, the pyrogallol ring as B, the galloyl moiety as B′, and ring C is the tetrahydropyran moiety. The hydrogen atoms attached to carbon atoms are also labeled. b, assigned one-dimensional ¹H NMR spectrum of EGCg in DMSO-d₆. c, a few strip plots from the two-dimensional NOESY with resonances assigned that belong to EGCg in complex with cCTnC·2Ca²⁺. The data were acquired in D₂O as to remove amide signals that predominate this region of the two-dimensional NOESY spectrum in H₂O. Details of the experiment are outlined in Table 1.
