What is Biochemistry? (2022)

Biochemistry is a discipline of Chemistry that deals with the chemical composition of living organisms. It deals with interactions between living organic cells and their surrounding fluids/matter and is the study of important chemical processes occurring within living organisms.

Biochemistry is the subdivision of Biology and chemistry that can further be divided into three segments, namely, metabolism, structural Biology and enzymology. By the end of the 20th century, these three variants together have been able to successfully explain the process of living.

It is the study of how living things are made, how they work, and what chemicals they have. It also looks at the human body's muscles and bones. In a Biochemistry Class, students can learn how cells are made or how blood works.

Thus Biochemistry helps in understanding the chemical basis that gives rise to the process through biological molecules that are occurring between the living cells and within the cells. This, in turn, relates to the understanding of tissues and organs as well as the structure of the organisms and their functions. Therefore, Biochemistry can alternatively be defined as the study of molecular Biology that relates to the molecular mechanisms of biological phenomena.

Biochemistry is the study of structures and the interactions of biological macromolecules. These macromolecules include protein, nucleic acids, lipids, and carbohydrates present in your body. As a result, Biochemistry is being used in research related to botany, medicine, and gene enhancement. Biochemistry is now working on finding the secret of life and how biological molecules boost the processes that occur within the living cells. This study will help in understanding the whole working organism.

Teaching, Science, researchers, analytical Chemist, and forensic scientist are all options for BioChemists. Let us see in detail the scope of Biochemistry.

Scope

The evolution of life that took us from the small microorganism to apes, to the humans which we have now become. All that study falls under one of the branches of Biochemistry. Besides, it is a study that is said to be the language of nature. All the tools that you see in the field of medical science are biochemical.

Biotechnology is using genetic engineering, which is one of the most sophisticated branches of chemistry. The use of biotechnology can be seen in the field of medical science, animal farming, pathological research, etc.

Lastly, one more branch we would like to mention is the medical Biochemistry, and this is one of the essential branches of the whole science as it deals with both the health and the disease of the human body. Every condition which the human body faces is biochemical because of every form of illness due to the abnormal behavior of chemicals and molecules present in the human body.

Students who want to become BioChemists should start by getting better grades in F.Sc pre-med. After that, the next step is to get into a 4-year bachelor's programme to get a Biochemistry degree.

The students get to study proteins and carbohydrates and enzymes and amino acids and lipids as well as DNA and RNA as their main subjects.

A BioChemist can work well for both the government and the private sector. They can even set up their labs with help from doctors who know what they're doing.

Today, Biochemistry is very popular in research fields, so BioChemists can work on hot topics to write about and publish later. They can also choose to be scientists or to be a member of a scientific group.

Now let us have a look at the wide scope of Biochemistry in different fields:-

Medical Science:- In order to understand various aspects of medical science like drug development, immunology, pathology, pharmacy, vaccine development, etc. it is important to have thorough knowledge about Biochemistry. After completing my bachelors in this particular subject one can lookout for a marketing executive in different pharmaceutical companies or as a lab assistant in private or government organizations. Also one can also become a medical coordinator for big pathology chains and various medical transcriptionists for different healthcare groups.

The clinical test done in the clinical laboratories is the main application area of Biochemistry. So one can join in as a pathologist in diagnostic centres relating to diagnostics, monitoring, and screening of patients. Another advanced part of Biochemistry is Genetic Engineering or Recombinant DNA Technology that deals with the development of several vaccinations. Thus one can join as a researcher in the research and development department with the big pharmaceutical companies after completing one Masters in Biochemistry.

Agriculture:- In order to understand the chemistry and the Biology of crops and medical plants, it is very important to have detailed knowledge about Biochemistry. The study of plant Biochemistry will lead a student to become a plant scientist in future. The main job of the plant scientist is to work towards developing high yield crops, isolating medical components from plants as well as producing disease resistant crops. After gaining thorough knowledge about the tissue culture of plants one can set up their own independent firm or nursery.

Food Industry:- To help the nutritionists in describing the different aspects of health-related to food consumption, the nutrition value of the food that is being consumed can be determined by the biochemist performing the biochemical tests. Also, the food analyst performs various studies that perform the proper measurement of carbohydrates, proteins, and fats. They also have the skills and knowledge to find out various adulterations done in the food industry. For the present Biochemistry students, a food security officer is a very important job prospect.
