    Study Notes

    Peptide Bond Characteristics

    • A peptide bond is a type of covalent bond, specifically an amide bond.
    • The molecular structures involved in a peptide bond are the carboxyl group of one amino acid and the amino group of another amino acid.

    Function of Peptide Bonds

    • The primary function of a peptide bond in proteins is to link amino acids together, forming a polypeptide chain.

    Geometry of Peptide Bonds

    • The geometry of a peptide bond is planar, meaning it is a flat, two-dimensional structure.

    Level of Protein Organization

    • The structural level of protein organization that involves interactions between peptide bonds is the primary structure.
