According to Balliet, “Biochemistry refers to the study of chemical processes and transformations in a living organism.” Biochemistry allows learners n understanding how chemical processes for example, respiration influences the functioning of all living organisms. The history of biochemistry is dated back to 1903 in which Carl Neuberg studied the transportation of soluble chemicals within cells and daily cellular processes. Biochemistry provides the scientific world with topics such as nutrition, medicine and microbiology, which aid in understanding the governing processes within a living cell. In other words, biochemistry helps in explaining the processes of life in relevance to how chemical interactions are used in supporting life. Over the last decades scientists have been able to study the complexity of life and successfully explained living processes included in life sciences through biochemical research. Subsequently, the main focus of pure biochemistry is to provide information that relates to the understanding and study of organs, tissues as well as whole organisms. In general, biochemistry is an instrumental subject in defining the complexity of living organisms and chemical processes within an organism.Biochemistry attempts to gain an understanding of the molecular levels of the chemical processes linked to living cells. In achieving these objectives, biochemists have isolated various molecules located within cells with the aim of determining and analyzing their general function as well as structures. In reference to these efforts, most features and characteristics of molecular levels and combination have been revealed. For instance, biochemists efforts to ascertain the molecular basis of the muscles cells have led to the identification of multiple molecules which are either complex or simple together with their detailed structure and whole functioning. Further, biochemistry attempts to develop an understanding of how life began. According to biochemistry ideologies, the beginning of a life incorporates chemical processes. Through this, chemical processes in human beings, birds, plants and micro organisms have been studied to grasp the complex forms of life in relation to human biochemistry.Historically, biochemistry is associated with organic chemistry which study’s the chemical properties of a compound which take part in living matter and functioning of living organisms. The facts and concepts in biochemistry are generated from various contiguous displine which are intimately related to the study of animate nature. Nonetheless, it has being widely termed as an independent branch of science whose main goals is to analyze and investigate the functional and structural inter relationship as well as the transmission of chemical compounds in a living cell. Additionally, biochemistry aims at identifying the roots taken during energy transformation, the regulation mechanisms of chemical conversions as well as the physio chemical processes which take place in organs, tissues and body cells. Moreover, biochemistry seeks to identify the molecular mechanisms which are applied during the transmission of genetic information in living organisms.Major categories in biochemistryBiochemistry incorporates numerous topics which are aimed at explaining, defining and studying the composition and components of living organisms. In biochemistry, the general topics include molecular biology, nutrition, medicine, animal and plant biology, genetics and cell biology. All these branches incorporate biochemistry discoveries which are instrumental in solving and understanding living organisms (Buchanan et al.). In this essence, nutrition is a branch of biochemistry which references essential requirements of life. This category highlights the need for a specific amount of proteins, lipids, carbohydrates, fats and amino acids for any organism to survive. The mentioned compounds are either fabricated or consumed by the organism in order to generate energy, cell structure, as well as other chemicals for survival.Subsequently, medicine is another topic studied in biochemistry and incorporates the effects of drugs and how they alter the chemical functioning in the human system. Doctors and nurses relate biochemistry when administering drugs to patients in order to help in preventing or curing the disease. When vaccines are administered to the human body, diseases are prevented because, biochemically, the body perceives the presence of a disease and respond to it. Pharmacy and pharmacology relies on the basis and knowledge of biochemistry. The metabolization of drugs through enzyme catalyzed reactions as well as the complex reactions that take place after administering of drugs can be best explained biochemically. Additionally, biochemical approaches have been widely applied in studying of diseases such as cell injury, inflammation and cancer with the aim of determining the appropriate and correct medicine to apply. In this essence, biochemical approaches have been exclusively employed in production of effective medicines used in treating various types of diseases. In other words, life entirely depends on the biochemical processes which take place in a living cell. Biochemistry enormously impacts the major medicine concerns. The relationship between medicine and biochemistry is far much wide as the biochemistry studies illuminates multiple disease and health aspects.Molecular biology is another topic which forms the root of biochemistry. Molecular Biology plays the role of instructing the living cells and systems on how to function effectively and support the entire body function. Molecular biology is widely termed as genetics. Biochemistry-molecular biology incorporates link between chemist and biology in their concerns for the composition of life cells. Molecular Biology involves understanding the significant process which takes place at the molecular level. This includes the transfer and storage of genetic information as well as the association of cells and viruses which infect them. the link between chemist and biology is aimed at building factual and conceptual understanding as well as intellectual skills on addressing current and future biochemical, and biological challenges. In molecular biology, the molecular and biological activities among bio molecules situated in cell system are studied to ascertain the relation between proteins, DNA and RNA and as well determine their biosynthesis and how these desired interactions are regulated. In genetics the genetically variations between organisms are studied as well as the translation and transcription.Cell biology is a branch of biochemistry which majorly concerns itself in identification of chemical basis of cells. The cell which is the structural unit of living cells is widely analyzed in the biochemistry field (Nelson et al). In biochemistry, chemical constituents in living cells such as enzymes, amino acids and nuclei acid are explicitly examined to define their functioning and structure. In cell biology, cells are termed as the store for the fundamental life molecules which make living organisms. Through the study of cell biology in biochemistry, the role of chemical compounds such as enzymes, amino acids, nuclei acid are explicitly analyzed to determine their functioning within the cells. Biochemically, cells metabolize their own nutrients, generate their own energy, synthesize various forms of molecules and eventually replicate in order to give rise to new cell. All these processes and reaction are linked to biochemistry in which chemical processes and reactions occur simultaneously. Biochemists have had a strong emphasizes in determination of biochemistry of plants and animal cells as well as the chemical events which take place within the cell of a living organism.Application of biochemistryBiochemistry is widely applied in pharmaceutical industry. This industry depends on biochemistry as the chemical composition of cells and body has to be evaluated in relationship to the chemical. A lot of medicines have been developed in relation to biochemistry researches which provide underlying medication assumptions and are significant in developing drugs. Biochemistry provides a base through which chemicals composed in drugs and medications are studied as well as the effects of drug on the body. Additionally, biochemistry topics such as cell biology and molecular biology play a significant role in knowing the type of chemicals needed in correcting imbalances when they occur in the body of a living organism.Biochemistry expertise thrives in the biotechnology field. This includes the utilization of living things in making and modifying products. Plant cultivation has been termed as the initial sample of biotechnology as well as precursor to the current genetic engineering, tissue and cell technologies. In other words biotech products are as a result of organic chemistry. In this essence, the food industry has greatly applied biochemistry concepts in developing foods which have nutrition value when consumed (Renu et al). Biotechnology has been applied in food and crop production, agriculture and healthcare. On the other hand, brewers and wineries have applied biochemistry approaches and theories in evaluating acids and yeasts which are used in manufacturing alcohol.Biochemistry have been widely applied in veterinary, dentistry and human medicine in studying the chemical composition of medicines and the fundamental changes which take place when drugs are administered. Additionally, biochemistry spreads to physiology, toxicology and micro biology through which researches are conducted in investigating drug action mechanism. Subsequently, biochemistry knowledge and skills have applicable in the production of chemical products such as herbicides and pesticides. With the help of biochemistry concepts, various materials and aspects for parasitic contamination have been used in parasitology.Another application of biochemistry is in gene therapy in the medical setting through which experimental techniques which utilize genes in preventing diseases are carried out. Gene therapy corrects defective genes which causes the onset of various diseases. Biochemistry approaches are, in turn, applicable in correcting of these faulty genes and ensuring the prevention of various infections such as cancer, viral infection and inherited disorders. With the help of biochemistry, gene therapies have been tested to come up with cures for diseases widely termed as cureless. Gene therapy has incorporated the clinical biochemistry to monitor and ensure its efficacy in disease progression.Importance of biochemistryBiochemistry is deemed to be a valuable subject which has greatly contributed to the advancement in the field of medicine. Firstly, biochemistry aids in understanding one’s biochemical changes which are in relation the physiological alteration of a person. This is associated with fact that, the pathology of any disease is examined through biochemical changes. In pathology, the study helps physicians to have a clue of a disorder which is associated to their patients based on the symptoms described. This subject is essential in treating nutrition deficiency scenarios through which the functions and roles of vitamins are only described by biochemistry. Subsequently, physicians are able to understand the role and formation of hormones in a normal body function through biochemistry and hence are able to understand many disorders in relation to hormonal imbalance.According to Kaneko et al, “clinical biochemistry is important in nursing as it allows nurses to observe the progress of the patient’s condition.” Also, through biochemical estimation, nurses are able to perform several clinical tests such as kidney function test, blood tests, serum and liver functioning tests. The significance of clinical biochemistry is to aid nurses to monitor the condition of the patients during treatment on a regular basis. Also, Biochemistry is importance in the study of plants as it provides a break through on how plants synthesis food and do not rely on living organism for food. Biochemistry in plants evaluates plant processes such as respiration, photosynthesis, germination and the plants secondary metabolism.In nutrition, biochemistry plays a significant role in health maintenance, regulating the intake of biochemical such as water, minerals, fatty acids and vitamins and describing the food chemistry. due to biochemistry the significance and contribution of nutrients is well known hence enabling diet recommendation by physician. Additionally, the nutrient value of different food materials has also been defined through biochemical tests. In other words, the adverse effects of certain food products have been determined on the basis of the food chemistry idea.In conclusion, the underlined principles of biochemistry is to develop knowledge on the structure of living systems and cells, their roles and functioning as well as the forms of controlling them. the biochemistry concepts have been widely adopted and applied in various industries as a source of knowledge and skills. The major topics in this branch include cell biology, molecular biology, medicine, plant and animal biology and nutrition. The demand for biochemistry knowledge in the scientific world is the desire to understand the medicine and microbiology fields and also to understand the life processes of living organism. Biochestry aims at providing underlying knowledge on the chemical molecules found within the body, their structures, function and interaction in a living organism. Biochemical techniques and approaches have been applied in researches and diagnostic labs. In general, biochemistry provides insight on the processes of life and how chemical processes and interaction help in supporting human life.Work citedBalliet E. “Definition of Biochemistry.” MedicineNet, 2017, www.medicinenet.com/script/main/art.asp?articlekey=15377.Buchanan, Bob B., Wilhelm Gruissem, and Russell L.
