how many elements are found in the human body
Ass you name the elements in the human body and what they practise? Nearly 99% of the mass of your human body consists of just 6 chemical elements: atomic number 8, carbon, hydrogen, nitrogen, calcium, and phosphorus. Other 5 elements make raised most of the last decimal point: potassium, sulfur, sodium, chlorine, and magnesium. Here's a take these elements in their pure form and their function in the anthropomorphic body. Billet that the portion are estimates. Hydration level (how much water you wassail) makes a big impact on the amount of atomic number 8 and H in your body and affects the relative composition of the rest of the elements in your dead body.
Periodic Set back of Per centum Composition of Elements in the Human Body
This periodic table shows the percent writing of the average human trunk. So, for example, oxygen accounts for 65% of the muckle of the physical structure, patc nitrogen is 3% and so forth. It's worth noting most of the noble metals are non found in perceptible quantities in the personify. Neither are the regal gases. In both cases, the deuce sets of elements are fairly inert. The a posteriori radioactive elements are missing, but a few natural radioactive elements, such as radium, thorium, and uranium are ground in trace quantities.

Function of Elements in the Body
Oxygen (O) – 65% of body burden
Atomic Number: 8
Oxygen is the most thick element in the human body. It's chiefly found bound to atomic number 1 in the form of pee. Water, in turn, makes up about 60% of the human body and participates in myriad biological process reactions. The element oxygen acts as an electron acceptor and oxidizing agent. It is institute in all four of the major classes of organic molecules: protein, carbohydrates, lipids, and nucleic acids. Because it is a key element in aerobic cellular cellular respiration, large amounts of oxygen are found in the lungs and in the bloodstream. Hemoglobin in blood bind the O molecule, O2, from inhaled air. Oxygen is used aside the mitochondria in cells to grow the push molecule ATP operating theater ATP. While it's essential for human life, too a great deal oxygen fanny be deadly, as it can lead to oxidative damage to cells and tissues.
Carbon (C) – 18% of body weight
Atomic Phone number: 6
Carbon is the instant most abundant element in the human body and the element that is considered the basis of organic chemistry. Every individualist organic molecule in your dead body contains C. The constituent bonds to itself to form irons and ring structures that serve every bit the basis for all metabolic reactions in the body. Carbon in carbon dioxide is expelled as a inhospitable product when you breathe.
Hydrogen (H) – 10% of body weight
Atomic Number: 1
Most of the hydrogen in the body is bound with atomic number 8 to form water, H2O. Atomic number 1, like carbon, is found in every single organic molecule in the body. H likewise acts as a proton or electropositive ion in chemical reactions.
Nitrogen (N) – 3% of body weight
Atomic Number: 7
Because about of air consists of N, nitrogen gas is found in the lungs, but it is not absorbed into the torso that mode. Humans get atomic number 7 from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an of import component of the nucleic acids Desoxyribonucleic acid and Ribonucleic acid and all of the different molecules derived from the nitrogenous bases.
Calcium (Ca) – 1.4% of body weight
Matter Number: 20
About 99% of the body's calcium is ground in maraca and teeth, where the element is used to build strong structural compounds, such as hydroxyapatite. Although most of the calcium is in bones and teeth, this is non the mineral's most important function. Calcium is an essential ion, victimised in muscular contraction and protein regulation. If any critical function has inadequate calcium, the consistence will actually drag it impossible of the bones and dentition. This can lead to osteoporosis and other problems, so it's decisive to get adequate dietary calcium.
Phosphorus (P) – 1% of body weight
Atomic Number: 15
Like atomic number 20, the element and mineral phosphorus is found in the bones and teeth. The element is besides base in nucleic acids and energy molecules, such American Samoa ATP (adenosine triphosphate).
Potassium (K) – 0.25%
Matter Amoun: 19
Electrochemistry in the body depends on ions. Of these, the cation potassium is among the most serious. Potassium is used in nerve conductivity and regulating the heart beat. All cells in the body expect potassium ready to role.
Sulfur (S) – 0.25%
Atomic Number: 16
Sulphur is establish in individual important amino acids, which are used to anatomy proteins in the body. S is found in biotin, methionine, thiamine, and cysteine.
Sodium (Na) – 0.15%
Atomic Number: 11
Sodium, like potassium, is an essential cation. This element is pivotal for nerve transmitting and muscle function.
Chlorine (Cl) – 0.15%
Atomic Amoun: 17
Chlorine is an measurable anion. Unrivaled of its functions involves the enthral of the enzyme ATPase, which is used to add energy for biochemical reactions. Chlorine is utilized to nominate hydrochloric acid, which is found in the stomach and digests nutrient.
Magnesium (Mg) – 0.005%
Atomic Phone number: 12
Magnesium binds to ATP and nucleotides. Its cation is an important cofactor for enzymatic reactions. Magnesium is secondhand to build healthy dentition and castanets.
Trace elements include iron, fluorine, zinc, silicon, rubidium, strontium, Br, run, cop, and many more. Some trace elements are essential or have a beneficial effect on the body, while others possess no known function or appear to be toxic.
