What is maturity? What is a disease? And finally, what is death? In short, answers to two of these most important questions can be cited here. Death is a state of disorganization of these elements. Among these many elements, only a few of them arrange in a specific order to give rise to life.

Any disorder in these elements results in a disease which may lead to death. Therefore, Biochemistry is the study of elements which make life and the fashion in which they are arranged. It also explains the functioning of these elements which trigger and continue the process of life.

The extent of de-arrangement of the life making elements, may either lead to disease or cause death. Medical professionals undertake Biochemistry in order to deal specifically with different methodologies of prevention and rectification of various disorders thus bringing back the body to function normally thereby helping in leading a healthy life and delaying the process of death.

In this article we will study the molecules forming the living matter and correlation of biological function with the molecular structure. From its study, Biochemistry has come to the conclusion that, matter in an appropriate physicochemical state of organization acquires the traits of living substances.

Let us now list out exactly those elements that form life.

The elements that give rise to life can be grouped into two categories:. The elements which are found in large quantities in the human body are major elements. They include the elements that are present in relatively appreciable amounts in the body, viz. They include the elements that are present in minute quantities in the body, viz. These elements combine in different ratios and proportions to make a molecule. For instance C, H, and O combine in ratio to make carbohydrates.

Similarly, C, H, O and N combine to form proteins and lipids.

Carbohydrates, proteins, lipids and nucleic acids, grouped under a category called macromolecules, form the basic components that make life possible.

In addition to these molecules there are micro-molecules like hormones, vitamins and minerals that also play a vital role in the process of life. Among the macromolecules, proteins and nucleic acids are known as informational macromolecules and the other two, viz. The areas of study of Biochemistry are the study of structure of these molecules, their properties, their functions, their inter-relationship and their metabolism. In order to study these characters it becomes necessary to isolate them, separate them, purify them and bring them into a suitable form so that it can easily be analysed and characterized.

Hence, Biochemistry also deals with methods and techniques to isolate, purify and characterize various compounds. Biochemistry deals not only at the molecular level but also at the level of the cell. A cell can suitably be defined as the theatre of life, where each and every artist molecules play their role functions exactly as the director DNA wants, and the director directs exactly as that appreciated and enjoyed by the audience cell organelles.

Biochemistry has proved that the above cooperation exists well for normal functioning of a cell and thereby of a living organism. A little misunderstanding between them leads to disturbances in the cell and finally may lead to death of the living organism. The main purpose of all the efforts of Biochemistry is to benefit humans in all forms, particularly in diagnosis and treatment of various diseases.

For example, measurement of serum levels of isoenzymes helps in the diagnosis and degree of various tissue disorders. Due to the knowledge of enzyme inhibition, it has become possible to treat various diseases.Biochemistrysometimes called biological chemistryis the study of chemical processes within and relating to living organisms.

A sub-discipline of both biology and chemistrybiochemistry can be divided into three fields; structural biologyenzymologyand metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed by biochemical methodology and research.

Biochemistry is closely related to molecular biologythe study of the molecular mechanisms of biological phenomena. Much of biochemistry deals with the structures, functions, and interactions of biological macromoleculessuch as proteinsnucleic acidscarbohydratesand lipidswhich provide the structure of cells and perform many of the functions associated with life. These can be inorganic for example, water and metal ions or organic for example, the amino acidswhich are used to synthesize proteins.

The findings of biochemistry are applied primarily in medicinenutritionand agriculture. In medicine, biochemists investigate the causes and cures of diseases. They also try to discover ways to improve crop cultivation, crop storage, and pest control. At its broadest definition, biochemistry can be seen as a study of the components and composition of living things and how they come together to become life. In this sense, the history of biochemistry may therefore go back as far as the ancient Greeks.

Some argued that the beginning of biochemistry may have been the discovery of the first enzymediastase today called amylasein by Anselme Payen[11] while others considered Eduard Buchner 's first demonstration of a complex biochemical process alcoholic fermentation in cell-free extracts in to be the birth of biochemistry. Emil Fischerwho studied the chemistry of proteins, [16] and F. Gowland Hopkinswho studied enzymes and the dynamic nature of biochemistry, represent two examples of early biochemists.

The term "biochemistry" itself is derived from a combination of biology and chemistry. It was once generally believed that life and its materials had some essential property or substance often referred to as the " vital principle " distinct from any found in non-living matter, and it was thought that only living beings could produce the molecules of life. These techniques allowed for the discovery and detailed analysis of many molecules and metabolic pathways of the cellsuch as glycolysis and the Krebs cycle citric acid cycleand led to an understanding of biochemistry on a molecular level.

Much like medical science itself, biochemistry is a vast area of research that yields profound discoveries each year.

Biochemical techniques advance our understanding of the chemical structures and processes that underpin human health and disease, revealing the underlying transformations between these two physiological states.

The implications of uncovering the causes of pathologies on a cellular level are huge. By being able to call on a working knowledge of biochemistry and other related disciplines such as molecular biology and immunology, those working in medical science have the potential to transform global healthcare.

And with the rise of public health threats such as air pollution and climate change, noncommunicable diseases, antimicrobial resistance, and dengue, the research of biochemists is needed more than ever. In this article, we pinpoint exactly why biochemistry plays such a central role in the life sciences — particularly in medicine.

As the name may suggest, biochemistry is a field of science that broaches the two traditional disciplines of biology and chemistry. If chemistry is the science of matter, then biochemistry is the science of living matter. Practitioners of biochemistry study the biochemical reactions that occur at the molecular level within living organisms. In medical biochemistry also known as molecular biologybiochemical techniques are applied to human health and disease.

The typical scope of medical biochemistry can encompass the following:. Much of biochemical inquiry deals with the structures, functions and interactions of biological macromolecules — large molecules such as proteins which provide the structure of cells and perform many of the functions associated with life.

The chemistry of the cell also depends on the reactions of smaller molecules and ions. These molecules can be organic e. Medicine is just one area that has benefited from biochemistry. The discipline has made vital contributions to the fields of including cell biology, physiology, pathology, pharmacology, microbiology, immunology, nutrition, forensic medicine, and toxicology, as well as the fields of inflammation, cell injury, and cancer.

Aside from medicine, biochemical research is also applied in industry, agriculture and food production. On a day-to-day basis, biochemists typically carry out research projects, manage laboratory teams, prepare technical reports and present research findings to scientists and key stakeholders.

Using electron microscopes, lasers and state-of-the-art laboratory instruments, they conduct experiments by analysing enzymes, DNA and other molecules.

These laboratory experiments cover a range of subjects, from extracting cell samples from plants and animals for genetic research to developing effective new medicines for the pharmaceutical industry. Once complete, the results are then analysed in an office environment using advanced data modelling software. Working in research teams alongside experts from other scientific fields, biochemists are predominantly employed across the life sciences sector including pharmaceuticals, biotech, toxicology, food technology and vaccine production.

They are also frequently employed in research roles in academic and government institutions. For anyone working in medicine or a related field, accruing sufficient biochemical knowledge is needed in order to properly understand the metabolismfunction and growth of a healthy human body. In physiology, the study of body function, biochemistry has broadened our understanding of how biochemical changes relate to physiological alteration in the body. It helps us understand the chemical aspects of biological processes such as digestion, hormonal action, and muscle contraction-relaxation.

In pathology, the study of how aberrant biochemistry relates to disease conditions in the human body, physicians can use biochemical analysis to confirm predictions based on patient testimony. For example, if a patient complains of sudden, severe pain in one or more joints, the physician may predict the problem to be gout — a form of arthritis caused by an excess of uric acid in the bloodstream. By measuring uric acid levels, biochemistry can then confirm whether gout is the root of the problem.

All diseases have a molecular basis, so biochemistry enables us to understand the chemical processes involved in conditions as varied as:.

Wit information gleaned from the chemical nature of pathologies, biochemists working in medicine are able to investigate potential treatments for diseases.

The action of a drug almost always involves some change in the biochemical processes taking place in the body. As such, pharmacologists must also be acquainted with the biochemical aspects of the human body.
