Most students who have been to Biology, Maybe studied Biochemistry as branch of Biology of Chemistry. In simple words you can say Biochemistry is Combination of Biology & Chemistry but in education, practical and technical terms it is defined this way.

A general perception is to study Biochemistry only if you want to make a career in Pharmaceutical or Lab Testing field. There more than 10 fields that requires basics to advanced level of study.

What is Biochemistry?

Biochemistry is a branch of chemistry which deals with the study of chemical composition in living organisms. Biochemistry being a study of the vital chemical processes occurring within living organisms and hence dealing with interactions between living organic cells with their surrounding fluids/matter

Biochemistry has branches that includes Molecular Biology, Immunology, Enzymology and genetics. A Biochemist can choose many career in their life like teaching, scientist, researchers, analytical chemist and forensic scientist.

Scholarly Biochemistry Definitions

  • Biochemistry is the study of structure, function and chemical composition of living beings

It includes studying Human Body Anatomy of both Muscles & Bones. In study of Biochemistry, you may be able to understand how cells are formed or what are blood properties

  • Biochemistry is the study of the structure, composition, and chemical reactions of substances in living systems. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry and began to study how living things obtain energy from food, the chemical basis of heredity, what fundamental changes occur in disease, and related issues. Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry [ref]
  • Chemistry that deals with the chemical compounds and processes occurring in organisms.
  • The chemical characteristics and reactions of a particular living organism or biological substance.

Branches of Biochemistry

Biochemistry is vast field of study. Every beginner after having basics go for further specializations depending upon their interests. Students willing to develop career as Lab Technician choose Blood Biochemistry and Molecular Biology. Being categorized into sub fields. Students are able to select any branch. These Branches of Biochemistry are Enzymology, immunology, Genetics, Molecular Biology, Plant Biochemistry, Animal Biochemistry, Metabolism, Cell Biology and Medical Biochemistry.

History of Biochemistry

Biochemistry is the study of life sciences in which we study about chemical structure and composition of living organism. Biochemistry is used in every field in science like Plant, animals and also humans study.

It was thought that its history started from in the era of Anselme Payen,who was a French chemist discovered diastase enzyme in 1833. Some arguments show that in 1842 Justus von Liebig give chemical theory of metabolism.

Justus Freiherr von Liebig (12 May 1803 – 18 April 1873) was a German chemist who made major contributions to agricultural and biological chemistry, and was considered the founder of organic chemistry.

As a professor at the University of Giessen, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of all time. [ref]

In 1987 first demonstration on Alcoholic fermentation was given by Eduard Buchner. He was a German Chemist as well as zymologist and He got noble prize in 1907.

Emil Fisher was a scientist who worked on chemistry of protein. George Beadle and Edward Tatum was scientist they work on this term that “one gene produce one enzyme only” and both got noble prize. There work was on fungi.

In the history of biochemistry the golden period was that in which scientist discovered gene. It was also said that history of biochemistry was started with ancient greek. Scientist also discovered enzyme and it lock and key mode.

They discovered macromolecules, macromolecule and that’s way they were able to tell about the chemical composition of living organism.

Application of Biochemistry

Biochemistry is used in everywhere in life like medical, plant, agriculture and nutrition etc.

Application in Agriculture

Increase fertility

By using biochemistry fertility can be increase. A agriculturist can used biochemistry tools to recognized plant condition and can experiments to enhance fertility.

Increase growth

By understand the reaction between pesticide and crop in the cell. Concept of biochemistry can help to increase the growth of plant.

Disease control.

Biochemistry can helpful to control disease in the field and give treatment of this disease. Different techniques are used to check disease in plant and it could be control.

In animal husbandry

It helps to diagnose the disease in animal and these disease could be control by using Biochemistry techniques.

Soil condition

If soil condition known fertility could be enhance. Biochemistry help to understand the condition of soil, their composition and deficiency and help to enhance soil condition.

Application in Medical

In medical mostly we study about different test

 Blood test

For hepatitis diagnosis serum or blood test is refer. This type of test is concerned with qualitative and quantitative liver function test. Blood glucose level test is for diabetic patient. CBC complete blood count is also helpful to understand patient health. For ketones body test urine test is referred.

Liver test

Biochemistry can help to understand the liver condition of patient. PCR test is used for qualitative and quantitative analysis. For diagnosis of HCC biochemistry techniques are used.

Pregnancy test

Biochemistry is also helpful to diagnosis of pregnancy. Human gonadotropin hormone which is made by placenta. This hormone is checked through urine test.


BHCG test is take through blood test to indicate pregnancy. This test diagnoses early pregnancy.

Kidney function test

For kidney urine test is take to check pH, change color of urine. These condition tells the problem of kidney.

AFP test

Alpha feto protein is a marker. This test is take in liver poor condition to check either patient has liver disorder or liver cancer.

ESR test

ESR test is used to check person health condition if its value will high its mean that there is inflammation in body.

These all above test used as biochemistry tools.

Scope of Biochemistry

Students who wants to choose the field of Biochemistry they must have pass out F.Sc pre-medical. Then they have to admit in bachelor 4 year program and completed their degree. As it has already discuss that what is Biochemistry?

Students study about protein, carbohydrate, enzyme, amino acid, lipids, DNA and RNA.

Biochemist can work in a private sector as well as in govt sector. Biochemist can open his private laboratory with collaboration of Doctors.  They can work on different latest topics in research field and can publish their work.

They could member of scientific society. They can choose as a career as a scientist.

How Can you Develop of Career in Biochemistry?

A biochemist can choose many careers

  • Physician associate
  • Toxicologist
  • Biomedical scientist
  • Analytical chemist
  • Biotechnologist
  • Healthcare scientist, clinical biochemistry
  • Clinical research associate
  • Forensic scientist
  • Nanotechnologist
  • Research scientist (life sciences)
  • Scientific laboratory technician
  • Biochemist can also choose career as a

Health and safety inspector

If Biochemist is a PhD holder or have a degree of post doctor He/ She can choose teaching field in a medical college if He / She meet their requirements.

With MPhil degree a biochemist can join teaching in a university or a college as a lecturer. Many fields are open for biochemist for job

Pay Scale

Fresher in the industry can expect $ 247  to $ 411.
Pay scale will increase according to experience.

Link with Biochemistry and Molecular Biology

Molecular Biology

As we know that in molecular biology we study about macromolecules like DNA, RNA etc. The study of biology on a molecular level including the structure, function, and makeup of biologically important molecules such as DNA, RNA, and proteins.

The field of molecular biology involves many other areas of biology such as biochemistry and genetics. Molecular Biology is a sub branch of Biology. But this interconnect with genetics and biochemistry.

In 1930 molecular Biology origin was found. When scientist was work on macromolecules. In molecular biology different techniques are used like PCR, CTAB DNA extraction, gel electrophoresis, northern blotting, and southern blotting, eastern blotting, and western blotting, microarrays and molecular cloning.

A lot of searches had been done in molecular lab.


As biochemistry is the study of chemical composition of living organisms. Biochemistry is the study of life science. In biochemistry we study general topics of lipids, protein, carbohydrates, amino acids etc.

Their structure and chemical composition.
