    Study Notes

    Understanding Biochemistry

    • Biochemistry is the study of chemical processes within and related to living organisms.
    • It merges biology and chemistry, focusing on the molecular mechanisms underpinning life.

    Emergence of Biochemistry

    • Biochemistry emerged as a distinct discipline in the late 19th century, gaining traction with the discovery of enzymes and biochemical pathways.

    Main Focus

    • The primary focus of biochemistry is to understand the structure, function, and interactions of biological molecules such as proteins, nucleic acids, lipids, and carbohydrates.

    Importance of Biochemistry

    • Studying biochemistry is crucial for advancing medical research, developing pharmaceuticals, and understanding metabolic disorders.

    Factors Leading to Biochemistry's Emergence

    • The increase in scientific knowledge, particularly in organic chemistry and the identification of biomolecules, facilitated the rise of biochemistry as a dedicated field.

    Cell Composition

    • Water typically constitutes about 70-90% of the weight of a typical cell, emphasizing its importance in cellular function and structure.

    Dominant Chemical Component

    • The predominant chemical component of living organisms is carbon, forming the backbone of organic molecules essential for life.

    Role of Water as a Solvent

    • Water acts as a biological solvent, facilitating biochemical reactions by dissolving various substances and enabling nutrient transport within cells.

    Water's Buffing Properties

    • Water's high specific heat capacity and ability to form hydrogen bonds contribute to its role as a buffer, regulating temperature and maintaining pH stability in biological systems.

    Medium for Biochemical Reactions

    • Biochemical reactions occur in aqueous environments, as water provides a suitable medium for the interaction of biological molecules.
