Relay Stations Placed Inside Proteins Can Carry an Electric Current

RELAY STATIONS PLACED INSIDE PROTEINS CAN CARRY AN ELECTRIC CURRENT 

The body contains several thousand different enzymes that are catalysts for specific bioreactions. Without them, biochemical pathways in the body would not function. 

Diabetics have a need for a glucose mete that would show the glucose concentration in the blood at any moment without having to take a sample. If the glucose builds up too much, the mete would send out a signal telling the wearer of the need 

One could carry this idea further. Since enzymes are so specific in reacting to only certain molecuies, one couid imagine a future generai diagnoser, a plaque with a series of enzymes adsorbed on miaoelectrodes that are exposed to the blood, with each able to pick out the molecules that indicate the presence of specific diseases. Oxidation reactions would provide electrons and an electrical signal would indicate the disease through the circuitry, which wouid identify the enzyme from which the current originated. For such an idea to work, one must have electronic conductivity of 

most enzymes are centered on a specific redox atom (e.g., Fe) and in order to be oxidized or reduced, the electron, the effector of the act, must travel through the enzyme to the so-called heme group, the vital Fe-containing group, as in hemoglobin, for example.
