    Study Notes

    Introduction to Biochemistry

    • Biochemistry is the study of the chemical composition of the human body

    Chemical Composition of the Human Body

    • The human body is composed of six main elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus (almost 99% of the body's mass)
    • Five additional elements are necessary for life: potassium, sulfur, sodium, chlorine, and magnesium (about 0.85% of the body's mass)
    • The remaining elements are present in smaller amounts (trace elements)

    Levels of Structural Organization in the Human Body

    • The human body is organized into several levels: atoms, molecules, compounds, cells, tissues, organs, and organ systems

    Compounds

    • A compound is a substance containing atoms of two or more different elements
    • Examples of compounds in the human body: water (H2O), proteins, carbohydrates, fats, and oils

    Molecules

    • A molecule is a group of atoms bonded together
    • Examples of molecules in the human body: oxygen (O2)

    Atoms

    • An atom is the smallest unit of matter
    • Atoms are the building blocks of molecules and compounds

    Water

    • Water is the principal fluid medium of the cell (70-85% of cell composition)
    • Water is an excellent solvent, participates in chemical reactions, absorbs and releases heat slowly, and serves as a lubricant
    • Properties of water:
      • Excellent solvent
      • Participates in chemical reactions
      • Absorbs and releases heat slowly
      • Requires a large amount of heat to change from a liquid to a gas
      • Serves as a lubricant
