    Study Notes

    Introduction to Biochemistry

    • Biology studies living organisms while chemistry is the study of matter, including its properties, composition, and reactions.
    • Biochemistry combines biology and chemistry to explore biochemical reactions and processes essential for life.
    • Biochemical processes occur within living cells and include numerous reactions organized in specific cellular organelles.

    Major Branches of Biochemistry

    • Medical Biochemistry
      • Examines the chemical basis of the human body, focusing on health and disease.
      • Analyzes how biochemical changes are related to various disease states.
    • Clinical Biochemistry
      • Studies diseases through the analysis of bodily fluids, such as blood and urine.
      • Supports diagnosis, therapy, and research in medicine.

    Other Branches of Biochemistry

    • Bacterial Biochemistry
      • Investigates chemical processes in microbes and how they metabolize nutrients.
    • Plant Biochemistry
      • Focuses on chemical processes and compounds in plants.
    • Animal Biochemistry
      • Studied chemical processes and substances within animals.
    • Industrial Biochemistry
      • Applies biochemical processes in industrial settings for producing pharmaceuticals, biofuels, and food products.

    History of Biochemistry

    • Biochemistry emerged in the late 18th to early 19th centuries.
    • The term "Biochemistry" was coined by Carl Neuberg in 1903.
    • Clinical Biochemistry developed as a distinct field in the 1940s.

    Pioneer Workers in Biochemistry

    • Significant contributions made by various scientists:
      • Berzilus: Enzyme catalysis.
      • Edward Buchner: Enzyme extraction.
      • Louis Pasteur: Fermentation processes.
      • Hans Krebs: TCA cycle.
      • Banting and Macleod: Insulin discovery.
      • Watson and Crick: Structure of double-stranded DNA.
      • Paul Berg: Recombinant DNA technology.
      • Karry Mullis: Polymerase chain reaction (PCR).

    Aims and Objectives of Studying Biochemistry

    • Understand the composition and role of various biomolecules in the human body, including their chemistry and location.
    • Determine the mode of action of biomolecules through isolation and structural elucidation.
    • Comprehend organized biochemical processes at the molecular and subcellular level.
    • Identify disease mechanisms by studying inherited metabolic disorders and oncogenes related to cancer.

    Principal Areas of Biochemistry

    • Structural Chemistry
      • Focuses on understanding the three-dimensional structures of biological molecules and their implications for function.
    • Metabolism
      • Examines all chemical processes that occur within living organisms for maintaining life.
    • Chemistry of Molecular Genetics
      • Investigates the chemical basis of genetic materials and their biological implications.
