  2. Bioelectromagnetics - Wikipedia

    en.wikipedia.org/wiki/Bioelectromagnetics

    Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...

  3. Evolution of metal ions in biological systems - Wikipedia

    The reactions in these cell compartments are glycolysis, photophosphorylation and carbon assimilation. ATP, the main source of energy in almost all living organisms, must bind with metal ions such as Mg 2+ or Ca 2+ to function. Examination of cells with limited magnesium supply has shown that a lack of magnesium can cause a decrease in ATP. [9]

  4. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...

  5. Iron in biology - Wikipedia

    en.wikipedia.org/wiki/Iron_in_biology

    The human body's rate of iron absorption appears to respond to a variety of interdependent factors, including total iron stores, the extent to which the bone marrow is producing new red blood cells, the concentration of hemoglobin in the blood, and the oxygen content of the blood.

  6. Human iron metabolism - Wikipedia

    en.wikipedia.org/wiki/Human_iron_metabolism

    The human body needs iron for oxygen transport. Oxygen (O 2) is required for the functioning and survival of nearly all cell types. Oxygen is transported from the lungs to the rest of the body bound to the heme group of hemoglobin in red blood cells. In muscles cells, iron binds oxygen to myoglobin, which regulates its release.

  7. Metalloprotein - Wikipedia

    en.wikipedia.org/wiki/Metalloprotein

    The abundance of metal binding proteins may be inherent to the amino acids that proteins use, as even artificial proteins without evolutionary history will readily bind metals. [8] Most metals in the human body are bound to proteins. For instance, the relatively high concentration of iron in the human body is mostly due to the iron in hemoglobin.

  8. Cofactor (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Cofactor_(biochemistry)

    This reduced cofactor is then a substrate for any of the reductases in the cell that require electrons to reduce their substrates. [32] Therefore, these cofactors are continuously recycled as part of metabolism. As an example, the total quantity of ATP in the human body is about 0.1 mole. This ATP is constantly being broken down into ADP, and ...

  9. Trace metal - Wikipedia

    en.wikipedia.org/wiki/Trace_metal

    A relatively non-toxic metal to humans and the second most abundant, the body has 2-3 grams of zinc. [1] It can enter the body through inhalation, skin absorption, and ingestion, [5] with the latter of the bunch being the most common. The mucosal cells of the digestive tract contain metallothionein proteins that store the zinc ions. [1]
