    Study Notes

    Proteins and Amino Acids

    • Not a function of proteins: undefined (awaiting specific information)
    • The sequence of amino acids in a protein is determined by the genetic code in DNA
    • A linear chain of amino acid residues is termed a polypeptide
    • A peptide is considered a linear chain of fewer than 50 amino acid residues, whereas a protein is a longer chain

    Biomolecules and Interactions

    • Amino acid residues are bonded together in a protein through peptide bonds
    • A macromolecule is a large molecule composed of many smaller molecules, such as proteins, carbohydrates, and nucleic acids
    • Hydrogen bonds maintain the structure of molecules by forming between a hydrogen atom and an electronegative atom
    • Biomolecules are composed of monomers, such as amino acids, sugars, and nucleotides
    • Hydrogen bonds are a type of molecular interaction that forms between a hydrogen atom and an electronegative atom

    Nucleic Acids

    • Nucleic acids, such as DNA and RNA, are composed of nucleotides as their macromolecules
