Chemistry of Life: A convergence of organic and Inorganic matter

The chemistry of life is very complex subject. Our body is made-up of very complicated chemical compounds built up from about one dozen elements. Several dozen chemicals produced from about a dozen basic elements make the living matter in unicellular as well as multi-cellular plants and animals. The most common elements, which are constituents of various organic and inorganic compounds in our body are: Hydrogen (H), Oxygen (O), Carbon (C), Nitrogen (N), Calcium (Ca), Phosphorus (P), Iron (Fe), Iodine (I), Magnesium (Mg), Sulphur (S), Sodium (Na), Potassium (K) and Chlorine (Cl). Sodium is the main constituent of the living matter in all body fluids in animals and human beings. Potassium is present in the cells in animals and humans but present in abundant in plants. Hydrogen and Oxygen are the constituents of water (H₂O). Water is the vehicle of life force as life is not possible without water. Hydrogen, Oxygen and Carbon are the constituents of carbohydrates. Proteins are composed of Hydrogen, Carbon, Oxygen, Nitrogen, Phosphorus and Sulphur, however all proteins do not contain Sulphur. Though we have been successful in analyzing the chemical constituents of living matter but life can not be created by just mixing of these chemicals. These chemicals act as a fuel for the propagation and preservation of life. Water and Oxygen have a vital role in creation of bioenergy and its transportation to various cells and tissues of the body. Exocrine and endocrine glands of our body play a vital role in the production and regulation of various bio-compounds required for normal health. Kidneys play excretory and regulatory function for maintaining a state of homoeostasis.
