Medical Mangan, iron, silver, copper and other metal in blood?

  1. Jun 22, 2012 #1
    I was recently asked why the iron in our blood wasn't killing us while iron is poisonous to the body; and what would be if it was other metals than iron in our blood, what would happen?

    How much silver do you have in your body, that doesnt sound right. Iron overload is bad, normal amounts iron in RBC is necessary for life

    Too much of any element is bad.

    Transition metals are in trace quantities within the body.

    Iron is part of hemoglobin.

    The element cobalt is essential to cobalamin (vitamin B12), a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins.

    "Classes of enzymes that have manganese cofactors are broad, and include oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, lectins, and integrins."

    Ceruloplasmin is the major copper-carrying protein in the blood.

    Chromium - "Chromium (III) is one of the trace elements, which are necessary for human and animal vital activity. It enters the organism from digestive tract and is transported to the tissues, where its accumulation takes place. The deficiency of chromium (III) causes the disturbances in metabolic processes. The primary reaction of organism on chromium (III) deficiency, is the lowered tolerance of glucose, which is the consequence of changes in insulin affinity to its receptors on cells. The considerable quantities of chromium (III) reveal in nucleic acids. It influences on their metabolism, replication and transcription. The ion decreases the content of corticosteroids in plasma and increases the functional activity of immune system of organism."

    "Your body needs just small amounts of trace minerals. These include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium."

    Silver has no known biological role.
