Categories: Periodic Element

HydrogenType: Major Element
Periodic Element: (H)
RDA: None listed
Importance- To Body:
A component of all organic molecules, as an ion (proton), it influences the pH of body fluids. The natural cycle of hydrogen production and consumption by organisms is called the hydrogen cycle.
Distribution- In Body:
9.5 Approx % Body Mass
Excess Effects:
Asphyxiation
Deficiency Effects:
None listed
Sources:
H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction between H2 and its component two protons and two electrons.
Sources Environmental/Geographic:
Hydrogen, as atomic H, is the most abundant chemical element in the universe, making up 75% of normal matter by mass and more than 90% by number of atoms.
