The term chemistry has its roots in alchemy, this being a set of practices in various areas of knowledge that sought to strengthen knowledge around the behavior of matter. The term was publicly known and socialized in 1661, through the publication of a book entitled “The Skeptic Chemist” by the Irish scientist Robert Boyle.

Although historically its concept has undergone several transformations, based on the complexity of the object of study that this area of ​​scientific knowledge was developing, today it is accepted that chemistry is a basic science in charge of observing and theorizing the behavior of matter and of the transformations that she undergoes from her interaction with the environment.

This science is of great importance for the development of other sciences such as biology, medicine, pharmacy, geology, engineering, and astronomy, among many other fields where it plays a leading role in its theoretical advancement.

What are the benefits of chemistry?

The benefits that the theoretical advances achieved by chemistry have brought to society are invaluable. Through this science, it has been possible to understand processes in the fields of human, animal and plant biology, as well as in the fields of spatial, environmental knowledge, and in other spaces of great significance for human life, which has allowed the eradication of conditions harmful development in the preservation and maintenance of man on earth.

Thus, chemical discoveries that have transformed the development of human beings in society, such as the appearance of fire, between 800,000 and 400,000 years ago, or pottery, 4,200 years BC, demonstrate their significance in the historical evolution of humanity.

More recently, the tuning of metal alloys, or materials such as fuel and plastic, the manufacture of medicines, or the study of the transformation of the matter that makes up the earth’s atmosphere, allow the construction of a welfare system for the development of the human species.

What is chemistry for in life?

Although it is not seen, chemistry is a matter that permeates daily life, since life itself is maintained through chemical processes, such as respiration and digestion. Likewise, the preparation of daily food can also be considered a chemical process, since it involves combining a set of substances that are synthesized into a product capable of providing calories to the body and keeping it alive.

On the other hand, a large part of the objects that surround the daily life of the human being were created from chemical processes, starting with the home, passing through the medicines that have to be ingested to cure a disease, and reaching the hygiene products personnel that are used from the moment people get out of bed to assume their daily routine.

What are the branches of chemistry?

As a science that has developed a broad field of study, chemistry is divided into two disciplines that respond to specific areas of research and theorizing: organic chemistry; and inorganic chemistry. This division is due to the need to develop specialized scientific fields in areas that respond to a specific type of knowledge.

What is organic chemistry for?

Organic chemistry is the branch of this science that is in charge of observing, investigating and theorizing regarding the matter constituted by carbon, which is why it is also called carbon chemistry.

The theoretical embryo that allowed the appearance of organic chemistry as a specialized discipline, historically is given to the German chemist Friedrich Wohler, when he synthesized urea in 1928 from the combination of other chemical elements. However, as early as 1856 William Henry Perkyn had accidentally synthesized the first organic dye called Pekyn Mallow.

From the point of view of the development of human life in society, it is perhaps the chemistry of oil that has the greatest economic relevance, since it is the main fossil fuel that moves the world. However, in the knowledge of processes of the human organism, it is organic chemistry that has developed the explanatory theoretical frameworks to promote the elaboration of medicines, for example, or devices and tools of perennial daily use, for example kitchen utensils, or the tools of the industry in general. Likewise, the main compounds in the development of life are of organic origin.

What is inorganic chemistry for?

Inorganic chemistry acquires its name in contrast to the object of study of organic chemistry, because in the stage of its appearance it was believed that all organic matter came from living beings. Therefore, inorganic chemistry observes, investigates and theorizes around matters devoid of carbon molecules, metals being the main components of its study.

The study spectrum of inorganic chemistry covers 40% of the interactions and reactions that occur in the molecular world of matter. Within the economic development of countries, this science finds its main scope in the following areas: mineralogy, geology, physical chemistry, environmental chemistry, analytical chemistry.

In everyday life, inorganic chemistry is found in essential elements such as common salt, soft drinks, batteries that use cell phones and other devices, and in soaps that are used as a household hygiene product.

What is blood chemistry for?

Blood chemistry is the method that is performed to assess the levels of vital elements present in the blood, allowing the conditions of the organs of the human body to be diagnosed. This domain of knowledge is used by medical science to determine a person’s health conditions.

Through the application of the tools and methods that blood chemistry has developed, information can be obtained that goes from the type of blood, to the screening of pregnancy, the characteristics of the internal organs of the human being and the presence of serious diseases.

The best-known techniques and methods are the following: the hemogram, which is a procedure that allows knowing the number and description of the kinds of cells found in a blood sample, allowing to observe conditions such as anemia; electrolytes, a procedure by which the amount of diluted minerals in the blood is measured, it allows to confuse disorders of the liver, heart and dehydration; cholesterol and triglycerides, with which risks are diagnosed in the circulatory system, particularly in the heart; glucose, allowing you to check blood sugar levels and mislead disorders such as diabetes.

What is analytical chemistry for?

Analytical chemistry is a branch of this science that seeks to structure knowledge about the molecular composition of a material. Two subdivisions of this branch are recognized: qualitative analytical chemistry and quantitative analytical chemistry.

This branch emerged at the end of the 18th century, as a consequence of the studies of chemical processes of certain materials, which allowed it to be recognized as a specialized area of ​​chemistry. The investigations of this branch of chemistry are based on the investigation of fast, sensitive and selective tools, since its main field of application, the industry, is always in the investigation of effective, efficient and economical methods.
