    Study Notes

    Biomolecules Overview

    • Four main types of biomolecules: Carbohydrates, Lipids, Proteins, and Nucleic Acids.

    Monomers

    • A monomer is defined as the basic building block of larger biomolecules.

    Importance of Biomolecules

    • Critical for metabolic processes, cell structure, energy storage, and genetic information transmission.

    Carbohydrates

    • Examples include starches (such as bread and pasta) and sugars (like table sugar and glucose).
    • Main function is to store energy.
    • Monomer form is monosaccharides.

    Lipids

    • Also referred to as fats.
    • Two primary building blocks: fatty acids and glycerol.
    • Examples include fats, oils, butter, cholesterol, and steroids.
    • Functions include storing long-term energy, cushioning and protecting organs, insulating the body, and forming cell membranes.

    Proteins

    • Numerous examples include meats, beans, cheese, eggs, nuts, and stomach enzymes such as pepsin.
    • Main functions consist of building and repairing muscle, facilitating body movement, and defending against germs or viruses.
    • Monomer unit is amino acids.

    Nucleic Acids

    • DNA plays a vital role; without it, a cell cannot synthesize essential proteins for life.
    • Examples include DNA and RNA.
    • Nucleotide serves as the monomer for nucleic acids.
    • DNA functions in storing and transferring genetic information.
    • RNA codes for amino acids and acts as a messenger between DNA and ribosomes for protein synthesis.
    • Nucleic acids are present in all forms of life.

    Chains of Biomolecules

    • Carbohydrate, lipid, and protein chains are composed of their respective monomers but need further elaboration.
    • Nucleic acids form extensive chains of nucleotides that create the overall structure of DNA and RNA.
