  2. Biological roles of the elements - Wikipedia

    en.wikipedia.org/wiki/Biological_roles_of_the...

    Biological roles of the elements. A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [ 1]

  3. Bioinorganic chemistry - Wikipedia

    en.wikipedia.org/wiki/Bioinorganic_chemistry

    Bioinorganic chemistry is a field that examines the role of metals in biology. Bioinorganic chemistry includes the study of both natural phenomena such as the behavior of metalloproteins as well as artificially introduced metals, including those that are non-essential, in medicine and toxicology. Many biological processes such as respiration ...

  4. Copper in biology - Wikipedia

    en.wikipedia.org/wiki/Copper_in_biology

    Copper proteins have diverse roles in biological electron transport and oxygen transportation, processes that exploit the easy interconversion of Cu(I) and Cu(II). [2] Copper is essential in the aerobic respiration of all eukaryotes. In mitochondria, it is found in cytochrome c oxidase, which is the last protein in oxidative phosphorylation.

Role(s) in nature (non-living and living) Role(s) in technology (old and new) 1: H: Hydrogen 1 1: Astronomy: source of power by nuclear fusion (proton–proton chain reaction and CNO cycle) Biology: One of the most common elements in living organisms: Petrochemical industry: hydrodealkylation, hydrodesulfurization

  7. Iodine in biology - Wikipedia

    en.wikipedia.org/wiki/Iodine_in_biology

    Iodine is an essential trace element in biological systems. It has the distinction of being the heaviest element commonly needed by living organisms as well as the second-heaviest known to be used by any form of life (only tungsten, a component of a few bacterial enzymes, has a higher atomic number and atomic weight ).

    Biometal (biology) Element percentages in the human body. Biometals (also called biocompatible metals, bioactive metals, metallic biomaterials) are metals normally present, in small but important and measurable amounts, in biology, biochemistry, and medicine. The metals copper, zinc, iron, and manganese are examples of metals that are essential ...
