Singing Ligands, Attuned DNA 2
“Like other proteins, which we discussed earlier, receptors have an inactive and an active shape and can shift back and forth between those conformations as the electrical charges are altered. When a receptor protein binds with an environmental signal, the resulting alteration in the protein’s electrical charges causes the backbone to change shape and the protein adopts an ‘active’ conformation. Cells possess a uniquely tuned receptor protein for every environmental signal that needs to be read.
-When estrogen is in its receptrors neighborhood, the estrogen receptor locks on to it, as surely as a magnet picks up paper clips.
-Similarly, histamine receptors complement the shape of histamine molecules, and insulin receptors complement the shape of insulin molecules.”
