Of note, and similar to Na + -dependent regulation of NKA activity described above, NCX was proposed to be subject to a secondary Na + -dependent inactivation following Na + binding to its inward facing transport sites in cardiac myocytes (Hilgemann, 2020)

The above considerations suggest that two pharmacologically distinct mechanisms with opposite effects on the same signaling pathway are involved in a normally unresolvable physiological failure (complete obstruction (ligation) of vessels and ischemia due to a cause that could be not removed, inadequate rescue and unable to heal)

Does this empty stomach rule apply to other oral peptides

The charged residues like glutamic acid, lysine, and the two aspartic acids enable specific interactions with cellular receptors and signaling molecules
