テオブロミンはmouse Tas2r121を活性化する予備的
範囲: Heterologous expression screen of 34 mouse Tas2r against 128 mostly natural bitter compounds
注記: Non-human receptor. Single study, single value; no EC50 for theobromine was located.
In Table 1, titled Threshold concentrations (mm) for Tas2r activators, the theobromine row carries a single value, 0.03, in the Tas2r121 column; all other columns are dashes.
限界: Mouse receptor, not human. Verified twice by narrow re-read that Table 1 columns are mouse Tas2r numbers only. No EC50 for theobromine is printed.
