    Study Notes

    Introduction to Biochemistry

    • Biochemistry studies chemical reactions and processes within living organisms.
    • Focuses on metabolic activities and life processes.
    • Term "biochemistry" introduced by Carl Neuberg in 1930, regarded as the father of biochemistry.
    • Combines biology and chemistry to analyze the chemical structures in living organisms.

    Key Areas of Study

    • Investigates chemical reactions involved in reproduction, heredity, metabolism, and growth.
    • Includes molecular biology and cell biology, relating to the molecular anatomy of cells and organs.
    • Explores carbon compounds and their reactions in living systems.
    • Addresses molecular physiology, focusing on how molecules meet cellular and organ needs.

    Major Branches of Biochemistry

    • Molecular Biology:

      • Examines functions of living systems, interactions between DNA, proteins, and RNA.
      • Explains synthesis processes in living organisms.

    • Cell Biology:

      • Also known as cytology, it studies cell structure and functions in living organisms.
      • Primarily focuses on eukaryotic cells and their signaling pathways, distinguishing from prokaryotic studies covered in microbiology.

    • Metabolism:

      • Critical process in all living beings involving the transformation of food into energy.
      • Includes activities such as digestion which exemplify metabolic processes.

    Introduction to Biochemistry

    • Study of chemical processes and reactions in the human body, relevant to metabolic activities.
    • Defined as the branch of science focusing on life processes like control and coordination in living organisms.
    • Term "biochemistry" was introduced by Carl Neuberg in 1930, known as the father of biochemistry.
    • Integrates biology and chemistry to research chemical structures and reactions involved in reproduction, heredity, metabolism, and growth.
    • Involves research in labs across molecular biology and cell biology.
    • Addresses molecular anatomy and physiology relating to the structures and functions of biomolecules like carbohydrates, nucleic acids, and lipids.

    Major Branches of Biochemistry

    • Molecular Biology:

      • Explains interactions between DNA, RNA, and proteins.
