Inorganic Compounds in the Body

There are two main classes of chemical compounds in chemistry and they are Inorganic and organic. More than a century ago, all substances then known were classified on the basis of source from which they were derived. The compounds which were of mineral origin were known as inorganic and those of vegetable or animal origin were called organic.

The inorganic compounds are the compounds in which they do not have carbon atoms in them. The inorganic compounds in the body are majorly containing water, O2, sodium chloride (NaCl) acids and bases. The trace amounts of inorganic compounds in the body are present and they are chromium, copper etc.,

Examples of inorganic compounds in the body are iron (Fe), Calcium (Ca), Magnesium (Mg), Phosphorous (P), Potassium (K) etc.,

Major Source of Inorganic Compounds in the Body

Water, oxygen and numerous salts are the inorganic compounds in the body. Water is the abundant inorganic compound available in the body. Since it is an excellent solvent, it is the main element which acts as a lubricant fluid in the body. Water absorbs the excess body temperature without undergoing any changes in it. It is useful in controlling the body temperature.

Water molecules have a high degree of cohesion because water molecules are held together by hydrogen bonds and hence due to this factor it contains strong surface tension. Due to this surface tension, it gives water strong capillary action, allowing water to creep up narrow tubing.

Water is a stable inorganic compound in the body, so it requires large amount of energy to warm it and remove a large amount of energy to cool. A large amount of heat is taken when sweat is evaporated which is formed on forehead in the body with it and the body is cooled.

Biological Importance of few Inorganic Compounds in the Body

  • Calcium (Ca) which is a constituent of bones and teeth is essential for vital metabolic processes such as nerve function, muscle contraction and blood clotting. Deficiency of calcium leads to Osteomalacia, Osteoporosis, Rickets, Tetany and formation of "stones" in the body especially the Gall Bladder and the Kidneys.

  • Iron (Fe) plays a very important role in the body, which is required for the transfer of oxygen between tissues in the body. Deficiency of iron causes Anemia, Increased susceptibility to infections.

  • Magnesium (Mg) is required for healthy bones, Functioning of muscle & nervous tissue; Needed for functioning for about 90 enzymes. Its deficiency causes Anxiety; Fatigue; Insomnia; Muscular problems; Nausea; Premenstrual problems. The most extreme deficiency may lead to arrhythmia.
