Biochemistry is an experimental science that aims to study chemical processes based on life. One girl’s biochemistry discipline, molecular biology, has experienced unprecedented growth over the last twenty years. Biochemistry is the study of the chemicals of living organisms. It has been closely associated with the great expansion in biological knowledge that has taken place during the twentieth century. Its importance lies in the fundamental understanding of how biological systems work.
It finds application in fields like agriculture, with the development of pesticides, herbicides, and so on; medicine, including the whole pharmaceutical industry; and fermentation industries, with their vast range of useful products, including dietetics, food production, and preservation.
Our understanding of biochemistry is underpinned by many exciting new developments in biology, like genetic engineering, biotechnology, ‘designer’ proteins, and molecular approaches to genetic disease.
Biochemistry: Comprahensive Details
Biochemistry, in its broad aspects, is the most comprehensive of all the branches of chemistry. It includes inorganic, organic, and physical chemistry, which is related to the chemistry of living things, both plants, and animals. The chemical principles involved in studying biochemistry are identical to those the student has learned in preliminary chemistry courses, but they are often posed in unique and intricate relationships.
The human body is composed of a few elements that combine to form various molecules.
C, H, O, and N are the major elements of most biomolecules. Calcium plays a major role in countless biological processes, and other elements having diverse roles are potassium, sulfur, sodium, chlorine, magnesium, iron, manganese, and iodine.
The cell is the basic unit of biology.
Understanding the molecular basis of the carrier of genetic information coupled with techniques for manipulating recombinant DNA has allowed biochemists to make breakthroughs in areas as diverse as human genetics, pharmacology, food, the environment, and evolution. Thus, biochemistry has contributed to the development of a new sector of the modern economy; biotechnology.
These techniques, associated with the structural study of macromolecules such as nucleic acids and proteins, allow modern biochemistry to unravel the deepest secrets of life. Here are the complete details covered in What is biochemistry?
What are BioMolecules, and What are they?
Only about 30 of the more than 90 naturally occurring chemical elements are essential to live organisms. Most of the elements in living matter have relatively low atomic numbers; only five have atomic numbers above that of selenium. The central atoms are hydrogen, oxygen, nitrogen, and carbon, which constitute 99% of the mass of most cells.
Six of the most abundant elements in the human body are also among the nine most abundant elements in seawater. Several elements abundant in humans are also components of the atmosphere and were, perhaps, present in the atmosphere before the appearance of life on earth.
Primitive seawater was most likely the liquid medium in which living organisms first arose. The primitive atmosphere was probably a source of methane, ammonia, water, and hydrogen, the precursors for the evolution of human life.
Biomolecules are compounds of carbon:
The chemistry of living organisms originated around the element carbon, and carbon accounts for more than half the dry weight of cells. Of greatest significance in biology is the ability of carbon atoms to share electron pairs to form very stable carbon-carbon single bonds.
Molecules containing covalently bonded carbon backbones are called organic compounds, which occur in almost limitless variety. Most biomolecules are organic compounds.
We can, therefore, conclude that the bonding versatility of carbon was a major factor in the selection of carbon compounds for the molecular machinery of cells during the origin and evolution of life.
Cellular details have been possible due to the increasing use of
- Electron microscopy,
- The introduction of methods permitting disruption of cells under mild conditions,
- High-speed, refrigerated ultracentrifuge
- DNA: The building block is deoxynucleotide; It functions as Genetic material
- RNA is made of ribonucleotide units and functions as a template for protein synthesis.
- Proteins: Made of Amino acids; Has numerous activities, e.g., Enzymatic, contractile elements, hormonal, structural, visual, etc.
- Polysaccharide: Units are glucose; Function as a storage form of energy as glucose
- Lipids: Fatty acid units; Numerous functions such as membrane components and long-term energy storage as triacylglycerols.

- Proteins – 17%
- Fat – 13.8%
- Carbohydrate – 1.5%
- Water – 61.6%
- Minerals – 6.1%

BIOCHEMISTS, SILENT HEROES OF MEDICINE
Without basic knowledge of the molecular basis of life revealed by biochemists, a few important discoveries that have led to advances in modern medicine have been possible.
Biochemists have made some major discoveries.
- The Discovery of the Structure of DNA: James Watson and Francis Crick
- The Discovery of Insulin: Frederick Banting and Charles Best
- The Discovery of Acetaminophen (Tylenol) by Julius Axelrod
- The Discovery of Cyclosporine (used as an anti-rejection drug in organ transplantation): Jean Borel
- Discoveries that led to the development of inhibitors of 5′-phosphodiesterase (Viagra): Robert F. Furchgott, Louis J. Ignarro, and Ferid Murad
- The Discovery of prions: a new biological principle of infection (due to mad cow disease ): Stanley B. Prusiner
Important discoveries in genetic engineering by Dr. Michael Smith, a Canadian, made possible the production and use of therapeutic proteins. This work earned him the Nobel Prize in Chemistry in 1993.
Challenges to overcome diseases that have been resisted are important. Meeting these challenges is part of the task of biochemists working in research.
What makes biochemists’ tasks on the day-to-day?
The biochemist makes a large variety of tasks, according to the orientation you choose and the work he plays. Tasks can range from collecting and studying laboratory tests; laboratory research; quality control and food; nutritional studies; study of the development, production, and control of pharmaceutical products; toxicological studies; research and development related to agribusiness products; control of epidemic diseases; etc. It is also often involved in theoretical research and teaching.

The subject requires a strong foundation in chemistry, biology, and mathematics and can be difficult for some students to grasp.
- Large Volume of Information: Biochemistry encompasses vast information, from the structures of molecules and the mechanisms of biochemical reactions to the regulation of metabolic pathways and the role of enzymes in cellular processes. This large volume of information can be overwhelming for some students and requires diligent study and retention of key concepts.
- Time-Consuming: Biochemistry is a time-consuming subject, requiring students to spend many hours in the laboratory conducting experiments, analyzing data, and writing reports. It can be challenging for students with other commitments, such as part-time jobs or extracurricular activities.
- Limited Career Opportunities: While biochemistry can lead to a rewarding career in academia, research, or industry, the job market can be highly competitive and limited in some areas. Students who do not pursue advanced degrees or gain specialized skills may find securing employment in the field challenging.
- Ethical Considerations: The study of biochemistry can also raise ethical considerations, particularly in genetic engineering and biotechnology. Students may need to grapple with questions of the ethical use of scientific knowledge and the potential impact of scientific advancements on society.
While working out is different, it depends on the state of development of some areas in the country where you carry out.
