Copper pipes, copper wires, copper…food? Copper is not only a useful metal for conducting electricity, but it’s also an essential element we need in our bodies for a variety of important activities—from metabolizing iron to pigmenting skin.

Copper is required to keep your body going. Enzymes that use copper are called cuproenzymes, and they catalyze a wide range of reactions, including making neurotransmitters and connective tissue. The element is found on the Statue of Liberty’s covering, in wiring and electronics, and in the blue blood of crustaceans. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.

The element potassium plays a pivotal role in our bodies. It’s found in all our cells, where it regulates their volume and pressure. To do this, our bodies carefully control potassium levels so that the concentration is about 30 times higher inside cells than outside. Potassium works closely with sodium, which regulates the extracellular fluid volume and has a higher concentration outside cells than inside. These concentration differences create an electrochemical gradient, or a membrane potential.

Potassium is the primary regulator of the pressure and volume inside cells, and it’s important for nerve transmission, muscle contraction, and more. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.

The element manganese is essential for human life. It’s aptly named after the Greek word for magic, and some mysteries surrounding its role in the body still exist today—like how our bodies absorb it, if very high or low levels can cause illness, or how it might play a role in certain diseases.

Manganese is necessary for metabolism, bone formation, antioxidation, and many other important functions in the body. The element is found in strong steel, bones and enzymes, and drink cans. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.

You may know that antioxidants can help protect your cells from oxidative damage, but do you know about selenium—an element often found in special proteins called antioxidant enzymes? Selenium is essential to your body, which means you must get it from the food you eat. But it’s a trace element so you only need a small amount to benefit from its effects. In addition to its antioxidant properties, it’s also important for reproduction, DNA synthesis, and hormone metabolism.
