Through all history the society has been trying to search out the ways to improve. Our life is full of different things that are the inventions of new science and technologies. The main object of almost every discovery that is performed by scientists is getting more knowledge about the visual environment. The classification of general term "science" comprises three kinds. The most considerable are natural sciences, exact sciences and social sciences. That is rather primitive classification as there are lots of smaller subclasses. But among the variety of sciences there are several leading sciences and sciences that drop behind. The most perspective sciences nowadays are medicine and biology.



The process of development of any medical systems or preparations is really complex and expensive but it is supported by many various organizations. You should understand that the most proper way to treat any disease is not to detect the disease and attempt to apply any medicines but to foresee the probability of person gets ill and remove the origins which can cause illness development. Now modern technologies give the possibility to scientists to determine accurately molecular mechanisms of illnesses. These processes are truly important and almost any disease may be simply treated in case we have enough knowledge about abnormalities that caused it.

Discoverers announce the there are some chemicals the human's organism can't do without. They are sodium, zinc, iron and copper. In case the quantities of these elements deviate form the norm it may produce some considerable consequences. For example it can be the disorder of metabolism. So the origin of a great deal of diseases is simply deviation of concentration of these substances from norm. The proper quantity of every matter is guarantee of normal processes' behavior. Reactions that are important for normal operating of the whole system can't be executed with no needed matters.

To maintain the normal vita processes of every organism it is essential to keep the organic molecules in appropriate form. There is a classification of organic molecules that are the indispensable part of any organism. The three types of organic molecules are oligomers, monomers and biological macromolecules. There are lots of researches carried out by lots of chemists that want to define the relations between the structure and characteristics in some substances. That is impossible to research such knowledge absolutely without the application of other sciences as physics, biology and mathematics.

We may mention that there are a lot of institutes in many various states that try to work together and carry out lots of researches. They can also carry out any drug discovery if it is requested by some medical organizations.

Scientists announce that if the humankind realizes the processes of synthesis of proteins and nucleic acids it will assist to treat many diseases. Not just the medical preparations are the achievements of today's chemical technologies. There are many different things that are used every day by us. You must have known that lots of up to date synthetic products have been existed just with help of the modern chemical knowledge.
