    Study Notes

    Introduction to Biochemistry

    • Coined in 1903 by Carl Neuberg, who is considered the father of modern biochemistry.
    • Neuberg's contributions include discovery of carboxylase and elucidating alcoholic fermentation as a series of enzymatic processes.
    • Biochemistry studies chemical substances in living organisms and their interactions.

    Principal Areas of Biochemistry

    • Structural Biochemistry: Investigates the relationship between the molecular structure of biochemical substances and their biological functions.
    • Metabolism: Examines all chemical reactions occurring in living organisms.
    • Molecular Genetics: Focuses on the chemistry behind processes that store and transmit biological information, aiming to understand heredity and genetic expression.

    Characteristics of Living Organisms

    • High chemical complexity and microscopic organization.
    • Biological structures have functional purposes.
    • Active energy transformations are ongoing within living systems.
    • Capacity for self-replication is inherent in living organisms.
    • Mechanisms present for sensing and responding to environmental changes.
    • Evolutionary changes are documented across living systems.

    Applications of Biochemistry

    • Medicine:
      • Physiology: Understands biochemical changes related to physiological alterations.
      • Pathology: Assists physicians in diagnosing disorders based on symptoms.
      • Hormonal Deficiency: Addresses disorders caused by hormonal imbalances.
    • Nursing:
      • Kidney function tests gauge drug excretion levels.
      • Liver function tests identify liver damage.
      • Blood tests measure glucose levels for diabetes severity.
      • Serum cholesterol tests assess cardiovascular disease risk.
    • Agriculture:
      • Facilitates disease prevention and treatment, enhancing crop yield and quality.
      • Informs fertilizer usage to boost plant growth.
    • Nutrition:
      • Analyzes food components such as carbohydrates, proteins, and fats.
      • Highlights the significance of vitamins, minerals, and essential fatty acids for health.
    • Pharmacy:
      • Biochemical tests determine the half-life and expiry dates of drugs.
      • Explains how drug molecules are metabolized through biochemical reactions.

    Cellular Biology

    • Cells are the smallest living units capable of performing life functions, observed only under a microscope.
    • Types of Cells:
      • Prokaryotic Cells:
        • Organisms are called prokaryotes, primarily bacteria.
        • Lacks a nucleus; has less defined structures.
        • Contains cell wall, outer membrane, and plasma membrane for material regulation.
      • Eukaryotic Cells:
        • Organisms known as eukaryotes, including animals, plants, fungi, and protists.
        • Characterized by the presence of a nucleus and various membrane-bound organelles.
