![]() ![]() The four key structural elements in human body (oxygen, hydrogen, carbon, and nitrogen) by weight, are often not included in the lists of major nutrient minerals (nitrogen is a "mineral" for plants, as it is often included in fertilizers). Anti-vitamins inhibit the actions or absorption of vitamins avidin inhibits biotin absorption, although it is deactivated by cooking Pyrithiamine inhibits enzymes that use vitamin B 1. Vitamins A and D can amass in the body, which may result in dangerous hypervitaminosis. In humans there are 13 vitamins: 9 water-soluble (8 B vitamins and vitamin C) and 4 fat-soluble (A, D, E, and K). Vitamin C can be synthesized by some organisms but not by others it is not a vitamin in the first instance but is in the second. Essential nutrients cannot be synthesized in humans, either at all or may be in insufficient amounts, and therefore must be obtained by the diet. Vitamins and minerals are essential micronutrients. For human nutrition, micronutrients are required in amounts generally below 100 milligrams per day, while macronutrients are required in gram amounts daily. Micronutrients are essential elements required by human and other organisms in varying quantities throughout life to coordinate a range of physiological functions for health maintenance. Macmillan.The research focused on the benefits of micronutrients (vitamins and minerals) and their associated deficiency diseases and health complications. Lehninger Principles of Biochemistry (5th ed.). The Biological Chemistry of the Elements: The Inorganic Chemistry of Life. Some trace elements are essential or have a beneficial effect on the body, while others have no known function or appear to be toxic. Trace elements include iron, fluorine, zinc, silicon, rubidium, strontium, bromine, lead, copper, and many more. Magnesium is used to build healthy teeth and bones. Its cation is an important cofactor for enzymatic reactions. Chlorine is used to make hydrochloric acid, which is found in the stomach and digests food. One of its functions involves the transport of the enzyme ATPase, which is used to supply energy for biochemical reactions. This element is important for nerve transmission and muscle function.Ĭhlorine is an important anion. Sodium, like potassium, is an essential cation. Sulfur is found in biotin, methionine, thiamine, and cysteine. Sulfur is found in several important amino acids, which are used to build proteins in the body. All cells in the body require potassium in order to function. Potassium is used in nerve conduction and regulating the heart beat. Of these, the cation potassium is among the most important. The element is also found in nucleic acids and energy molecules, such as ATP (adenosine triphosphate).Įlectrochemistry in the body depends on ions. Like calcium, the element and mineral phosphorus is found in the bones and teeth. Phosphorus Allotropes (Materialscientist) The table is available to print as a PNG image file or as a PDF file. The synthetic radioactive elements are missing, but a few natural radioactive elements, such as radium, thorium, and uranium are found in trace quantities. In both cases, the two sets of elements are fairly inert. It’s worth noting most of the noble metals are not found in detectable quantities in the body. So, for example, oxygen accounts for 65% of the mass of the body, while nitrogen is 3% and so on. This periodic table shows the percent composition of the average human body. The values correspond to the element’s mass fraction in an average human body. Periodic Table of Percent Composition of Elements in the Human Body Periodic table showing the elements in the human body. ![]() ![]() Hydration level (how much water you drink) makes a big impact on the amount of oxygen and hydrogen in your body and affects the relative composition of the rest of the elements in your body. Here’s a look at these elements in their pure form and their function in the human body. Another 5 elements make up most of the last percentage point: potassium, sulfur, sodium, chlorine, and magnesium. This entry was posted on by Anne Helmenstine (updated on May 2, 2021)Ĭan you name the elements in the human body and what they do? Nearly 99% of the mass of your human body consists of just 6 chemical elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. ![]()
