How do molecules work
WebThis cell communication is transferred via; hormones, chemicals, neurotransmitters, neuropeptides, cell receptors and many other biological actions keeping you alive and flourishing. Redox signaling molecules are activator molecules and more specifically, carry the messages that tell your cells to activate antioxidants stored in your body. WebFree radicals are harmful molecules with unpaired electrons that seek to scavenge more electrons from other molecules, causing damage to DNA enzymes, proteins and cell membranes. SOD, as an antioxidant, works to donate an extra electron to the free radicals, therefore preventing any future damage that the free radical would have done.
