Polysaccharides (saccharides are carbohydrates) correct answers Polymer of monosaccharides Peptide bond correct answers Bond between amino acid residues to form a polypeptide chain. (Amide linkage) Phosphodiester bond correct answers Bond that connects nucleotides together to form nucleic acids Glycosidic bond correct answers Any bond that links a sugar to something else Hydrogen bond donor correct answers A hydrogen bonded to an electronegative atom Hydrogen bond acceptor correct answers a lone pair of electrons associated with an electronegative atom Van der Waals interactions correct answers a composite of weak intermolecular forces consisting of dipole dipole and London dispersion forces. Strength of bond types listed strongest to weakest (Covalent, Hydrogen bonds, van der waals, ionic) correct answers Covalent, ionic, hydrogen bonding, Van der Waals Hydrophobic effect correct answers The inability of polar molecules to form hydrogen bonds with non polar molecules, therefore resulting in the tendency of polar compounds to associate with each other in aqueous environments. What makes for dynamic water? Why is it preferable? correct answers Extensive hydrogen bonding leads to dynamic water, it is preferable because it has a lower energy state than interrupted water.
