  • What is the main function of lipids?

    Lipids function in long-term energy storage, membrane structure, and signaling.

  • What are common examples of lipids?

    Examples include fats, phospholipids, and steroids.

  • What are the building blocks of nucleic acids?

    Nucleotides are the building blocks of nucleic acids.

  • What is the main function of nucleic acids?

    Nucleic acids store and transmit genetic information.

  • What are common examples of nucleic acids?

    Examples include DNA and RNA.

  • What are the building blocks of proteins?

    Amino acids are the building blocks of proteins.

  • What is the main function of proteins?

    Proteins function as enzymes, structural components, and signaling molecules.

  • What are common examples of proteins?

    Examples include enzymes, antibodies, and hemoglobin.

  • What is the primary structure of a protein?

    The primary structure is the linear sequence of amino acids in a polypeptide chain.

  • What is the secondary structure of a protein?

    The secondary structure includes local folding into alpha helices and beta sheets stabilized by hydrogen bonds.

  • What is the tertiary structure of a protein?

    The tertiary structure is the overall 3D shape of a single polypeptide, formed by interactions among side chains.

  • What is the quaternary structure of a protein?

    The quaternary structure is the arrangement of multiple polypeptide subunits into a functional protein complex.

  • How can proteins be denatured?

    Proteins can be denatured by heat, pH changes, chemicals, or mechanical forces, disrupting their structure and function.
