    Study Notes

    Introduction to Macromolecules

    • Macromolecules are large molecules found in all living things, from bacteria to elephants.
    • There are four main classes of macromolecules: carbohydrates, nucleic acids, proteins, and lipids.
    • Nucleic acids, proteins, and carbohydrates are huge molecules, therefore called macromolecules.

    Monomers and Polymers

    • Monomers are smaller molecules that serve as building blocks of a polymer.
    • When a bond forms between two monomers, each monomer loses a part of the water molecule, releasing a hydroxyl group and a hydrogen atom.
    • This reaction is repeated as monomers are added to the chain, making a polymer through dehydration or polymerization.

    Dehydration Reaction

    • Dehydration reaction is a process where monomers are bonded together to form a polymer, releasing a water molecule.
    • This reaction is repeated as monomers are added to the chain, making a polymer.

    Hydrolysis

    • Hydrolysis is the reaction where polymers get disassembled to monomers.
    • This process is the reverse of the dehydration reaction.
    • The bond between monomers is broken by the addition of a water molecule, releasing a hydrogen and a hydroxyl group.

    Importance of Macromolecules

    • Inherited differences between close relatives, such as human siblings, are because of small variations in polymers, particularly DNA and proteins.

    Biological Processes

    • Hydrolysis occurs in the process of digestion within our bodies.
    • Enzymes, which are specialized proteins, facilitate dehydration and hydrolysis reactions in cells.
