Poisons
Many poisons have a structure like 3 methols attached to 1 Carbon. ACTH is the mediator Take the case of Cyanide: it is a poison because it has high affinity to the HEME, and changes the heme so it is unable to carry O2. And does so irreversibly. Lethal 20 mg/kg --a drop how many molecules and EACH MOLECULE can kill one horse How many? (trillions)

BOX Tzar tried to kill Rasputin Put poison in a cake, but Rasputin lived, because the poison interacted with cake fat. If you have lead poisoning you should drink drink milk because milk has so many proteins with affinity for heavy metals.
