    Study Notes

    Biomolecules Composition

    • Biomolecules are primarily composed of carbon, hydrogen, oxygen, and nitrogen
    • Carbon is the primary element in biomolecules due to its unique ability to form long chains and rings with itself and other elements
    • This ability allows for the formation of complex molecules with diverse functions

    Biological Importance of Carbon

    • Carbon's high bonding capacity and stability make it an ideal element for the formation of biomolecules
    • Its ability to form long chains and rings allows for the creation of complex molecules with diverse functions

    Protein Building Blocks

    • The building blocks of proteins are amino acids, which are linked together by peptide bonds
    • There are 20 standard amino acids that combine to form proteins

    Elemental Composition of Organisms

    • Carbon, oxygen, nitrogen, and hydrogen make up more than 97% of the weight of most organisms
    • These elements are the primary components of biomolecules and are essential for life

    Biological Chemistry

    • The chemistry of biological systems is known as biochemistry or biological chemistry
    • Biochemistry studies the chemical processes and transformations that occur within living organisms
