12 Real-Life examples from Biochemistry

Biochemistry is the branch of science that studies the chemical processes that occur within and around living organisms.

It is an important area of study as it gives us a deeper understanding of the workings of living organisms at the molecular level. It plays a crucial role in our lives as it helps us understand the mechanisms behind various physiological processes and diseases, allowing us to develop treatments and cures.

Biochemistry has many applications in medicine, agriculture, and food science. In this article will explore the significance of biochemistry through real-life examples, providing a clearer understanding of the subject and its impact on our daily lives.

Main Branches of Biochemistry

The main branches of biochemistry are:

Metabolic Biochemistry

A study of metabolic biochemistry involves studying the chemical processes that occur within living organisms and which are essential for their survival, such as energy metabolism. This category covers all activities associated with generating, storing, using, and converting energy and synthesizing hormones and enzymes.

Studying metabolic processes such as glycolysis, gluconeogenesis, and the electron transport chain is also an important aspect of metabolic biochemistry.


Enzymes are proteins that catalyze chemical reactions in living organisms, and the study of enzymes is called enzymology. Enzymes regulate many chemical reactions, such as the breakdown of carbohydrates and the synthesis of proteins; for example, the enzyme amylase helps break down starch molecules into simple sugars.

Since enzymes are essential to metabolic processes and are linked to numerous diseases, enzymology is a vital area of study in biochemistry.

Structural Biochemistry

Structural biochemistry examines the three-dimensional structure of biomolecules like proteins, carbohydrates, and lipids. The molecular structure can be studied using X-ray crystallography, nuclear magnetic resonance spectroscopy, and molecular modeling. The structure of a molecule is the key to unlocking its function, interactions, and potential role in disease.


The field of bioinformatics is fast growing as it combines computer science and biology. It analyzes many biological data, such as DNA sequences, protein structures, and gene expression patterns.

Bioinformatics algorithms are developed to predict protein structure, identify gene function, and detect genetic mutations. Biological data generation continues to grow exponentially, making this field increasingly important.

Clinical Biochemistry

Clinical biochemistry is the branch of biochemistry concerned with studying, preventing, and curing human illness. Diagnosis of metabolic disorders like diabetes, cardiovascular disease, and hepatitis involves the analysis of biochemical markers in the blood and other tissues, such as glucose, cholesterol, and enzymes.

Developing new treatments for diseases based on a biochemical understanding of underlying causes is also part of clinical biochemistry.

Molecular Biology

DNA, RNA, and proteins, as well as their structure, function, and interactions, are the focus of molecular biology. Much of what we know about how genes shape an organism’s traits comes from this biochemistry subfield.

Genetic engineering and the use of manipulated genetic information in medicine and agriculture are also part of the realm of study influenced by molecular biology.

Nutritional Biochemistry

Nutritional biochemistry is the study of nutrients and their function in health and disease prevention. Nutritional biochemistry examines the interplay between vitamins, minerals, and other essential substances and the molecules with which they interact.

How nutrients are absorbed, transported, stored, and used in the body are all aspects of nutrient metabolism that fall under the scope of nutritional biochemistry.


Toxicology is the scientific study of how poisons affect living things. This field falls under the evaluation of chemical and drug safety, understanding the mechanisms of toxicity, and creating treatments for poisonings. An understanding of toxicology involves the study of biochemistry, pharmacology, and pathology to determine how toxins harm living things.

These branches of biochemistry share a wide range of similarities and overlapping concepts. Scientists in the medical, agricultural, and environmental fields can benefit from biochemists’ better understanding of living organisms’ chemical processes.

Here are some examples of biochemistry:

Enzyme production

The production of enzymes is necessary for biofuels, food and beverage processing, laundry detergents, and many other chemical reactions in the body. Enzymes are crucial to many biological processes, and biochemists work to better understand their structure and function to create efficient methods for mass-producing them.

Drug design

Biochemists’ research into biochemical processes related to diseases is crucial to developing more effective medicines. Therefore, they play a vital role in this area. Design and synthesis of new drugs, and improvements to the efficiency and safety of existing drugs, fall under this category.

Genetic engineering

Biochemists use their understanding of genetics and molecular biology to modify the DNA of living organisms. For instance, biochemists can use gene-editing techniques such as CRISPR to alter the genetic code of plants and animals and create organisms with desired traits. This is done for many reasons, including developing new medicines, enhancing agricultural production, and environmental restoration.

Food science

In food science, biochemists determine the chemical composition of food, determine which nutrients are necessary, and examine the metabolic processes that affect its breakdown and absorption.

“Food research” refers to the study of food and its components, including developing new products, refining existing processing techniques, and evaluating food additive safety.


The use of microorganisms for cleaning up environmental contaminants, such as oil spills, hazardous waste sites, and contaminated groundwater, is a field of study for biochemists known as bioremediation. It requires research into microbial metabolism and fine-tuning various environmental parameters so that productivity can be maximized.


Researchers are working on perfecting biomaterials for use in medicine and industry, including biodegradable plastics, artificial tissues, and nanoscale materials. Through research into the interactions between biological molecules and these materials, new synthetic materials have been developed that are more biologically friendly.


Metabolomics is the study of metabolic profiles in cells, tissues, and organisms using cutting-edge analytical methods like mass spectrometry, which biochemists study. Research on metabolic biomarkers for cancer and diabetes and the investigation of metabolic processes are among these areas of study.


The identification of protein interactions, the determination of protein structures, and the development of new protein-based drugs and diagnostic tools all fall under the umbrella term proteomics, which is the study of the structure and function of proteins, the building blocks of life.

System biology

In systems biology, biochemists model the interaction of various biological systems through computer algorithms, such as metabolic networks and gene regulatory networks. This includes the identification of key biological processes, the forecasting of biological responses to environmental changes, and the creation of improved treatments for existing diseases.


Neurochemistry is the branch of biochemistry concerned with studying the chemical processes involved in the functioning of the nervous system, including the neurotransmitters involved in brain signaling and the biochemical processes involved in brain development and function.

Research into neurological diseases like Alzheimer’s and Parkinson’s, and the creation of effective treatments for them, fall under this category.

Cancer biology

Biochemists in the field of cancer biology investigate the molecular and cellular mechanisms that contribute to the disease, such as detecting carcinogenic genes and identifying their associated signaling mechanisms. This includes studying metabolic changes related to cancer growth and progression and creating new cancer therapies like targeted drugs and immunotherapies.


The study of bioenergetics, or how organisms obtain and use energy, relies heavily on biochemistry. The primary energy currency of cells is ATP, which is produced through biochemical processes such as glycolysis, the Krebs cycle, and oxidative phosphorylation.

Energy production and utilization in cells and the discovery of effective treatments for metabolic disorders depend on our ability to understand the complex mechanisms that control them.
