The Chemistry of Life: This occasional series of articles looks at the vital things in our lives and the chemistry they are made of.
You are what you eat. But do you recall munching some molybdenum or snacking on selenium? Some 60 chemical elements are found in the body, Chemistry in our life what all of them are doing there is still unknown.
Roughly 96 percent of the mass of the human body is made up of just four elements: The remaining 4 percent is a sparse sampling of the periodic table of elements. Some of the more prominent representatives are called macro nutrients, whereas those appearing only at the level of parts per million or less are referred to as micronutrients.
The FDA has set a reference daily intake for 12 minerals calcium, iron, phosphorous, iodine, magnesium, zinc, selenium, copper, manganese, chromium, molybdenum and chloride. Sodium and potassium also have recommended levels, but they are treated separately.
However, this does not exhaust the list of elements that you need. Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. And there are several other elements — such as silicon, boron, nickel, vanadium and lead — that may play a biological role but are not classified as essential.
Sometimes all that is known is that lab animals performed poorly when their diets lacked a particular non-essential element. However, identifying the exact benefit an element confers can be difficult as they rarely enter the body in a pure form.
A normal diet consists of thousands of compounds some containing trace elements whose effects are the study of ongoing research. For now, we can only say for certain what 20 or so elements are doing.
Here is a quick rundown, with the percentage of body weight in parentheses. Its central role is due to the fact that it has four bonding sites that allow for the building of long, complex chains of molecules.
Moreover, carbon bonds can be formed and broken with a modest amount of energy, allowing for the dynamic organic chemistry that goes on in our cells. It helps regulate the heartbeat and is vital for electrical signaling in nerves. It also regulates the amount of water in the body.
This electrolyte is important for maintaining a normal balance of fluids. It also is necessary in more than essential metabolic reactions. It is also found in hemoglobin, which is the oxygen carrier in red blood cells. Outside of preventing tooth decay, it does not appear to have any importance to bodily health.
Several proteins contain structures called "zinc fingers" help to regulate genes. Zinc deficiency has been known to lead to dwarfism in developing countries.
Iodine deficiency, which can lead to goiter and brain damage, is an important health problem throughout much of the world.Editor's Note: This occasional series of articles looks at the vital things in our lives and the chemistry they are made of.
You are what you eat. Chemistry is present in every aspect of life, and here you can see a few examples. There are articles about the chemistry of everyday life, and also a few about physics, as it's also present in our daily life. Visit us at an open day. Book an open day place.
Visit our campus, meet your new chemistry lecturers, experience the facilties you will be using as a student and find out more about our chemistry courses.
Welcome to the Department of Chemistry at Millersville University. Our American Chemical Society approved programs of study offer students the opportunity for a basic and comprehensive study in the field of chemistry.
There are many examples of chemistry in daily life, showing how prevalent and important it is. Digestion relies on chemical reactions between food and acids and enzymes to break down molecules into nutrients the body can absorb and use. Chemistry is indeed in our everyday.
You yourself are a big bag of chemicals! What is astonishing is the amount of applications we make of the gruelling formulae from our chemistry class in our everyday life.
