Biomolecules 'A Brief Review'


All the living bodies are composed of several lifeless substances which are present in their cells in a very complex and highly organized form. These are called bio-molecules. Some common examples are carbohydrates, proteins, enzymes, nucleic acids, lipids, amino acids, fats,etc. The molecules combine in specific manner to produce life. Many of the bio-molecules are polymers. For example, starch, proteins, nucleic acids are condensation polymers of simple sugars, amino acids and nucleotides respectively.

Most of the biochemical reactions take place in dilute solutions(with pH near 7) at body temperature (nearly 37 C) and at 1 atmospheric pressure. These biochemical reactions are very complex and highly selective. Bio-molecules are related to living organisms in the following sequence :

LIVING ORGANISMS----> ORGANS----> TISSUES----> CELLS----> ORGANELLES----> BIO-MOLECULES.

The second picture represents the structure of DNA(deoxyribo nucleic Acid).

Chemistry in Our Everyday Life



Chemistry plays an important role in our everyday life. Since the beginning of this branch of science, it has been in the service of mankind. Our daily needs of food, clothing, shelter, potable water, medicines, etc. are in one or other manner connected with chemical compound, processes and principles. 

We always owe a debt to chemists for their important contributions for giving us life saving drugs, synthetic fibers, synthetic detergents, variety of cosmetics, preservatives for our food, fertilizers, pesticides, paper, glass, strength materials, plastics, beautiful paints,etc. There is no aspect of our life that is not affected by the developments in chemistry. In fact, chemistry is the single branch of science which profoundly influences the existence of human beings and the habitat. Thus, the mankind owes much to chemistry because it has improved the quality of life.

The chemical substances used for treatment of diseases and for reducing suffering from pain are called medicines or drugs. The term chemotherapy is used for the science in which suitable chemicals are used for the treatment of diseases. These chemicals have specific effect for destroying the invading organisms without injuring the cells of the body. In the ancient practices of treatment of diseases like Ayurvedic, the Unani systems or the modern allopathic system, the drugs used are chemical compounds of natural or synthetic origin.

How to know your IP Address

IP address means Internet Protocol Address is a unique number which is assigned to every device which is connected to internet. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and look something like 124.456.789.123.


Since these number's are assigned to regional based blocks, an IP address can usually be used to identify the region, city, state or country from where computer is connected to internet. An IP address can sometimes be used to track the information of the user who is being using that service connected to internet without knowing him/her. These numbers are also assigned to a host name which are sometimes easier to remember so that one can remember his IP address. At one time only one IP address can be issued to that person who is using internet. These are called static IP addresses. Also, the users connected to internet, with virtual hosting, a single machine can act as multiple machines i.e with multiple domain names or multiple IP addresses.


You can also find your IP address of our area in which your computer is connected to internet simply by going to the site given below.
