hydrogen bonds.
"Hydrogen bonds also play important roles in determining and maintaining the three-dimensional shapes of giant molecules such as DNA and proteins..." From the Biology text "Life, the Science of Biology" by William Kirkwood Purves
hydrogen bonds
Hydrogen bonds are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.
Hydrogen bonds are considered weak bonds, however in large biochemical molecules, they can act as a stabilizer. An example is a protein, which contains numerous weak bonds (Hydrogen, van der Waals, and hydrophobic), after the primary structure.
Hydrogen bonds hold cellulose molecules together in bundles large enough to form fibers..
Ionic bonds is the attracting between opposing forces (positive and negative) while covalent bonds are atoms sharing electrons to get an inert gas configuration (8 electrons in valence shell). Covalent bonds exist as discrete molecules while ionic compounds do not exist as discrete molecules and form large crystal lattices.
The intermolecular force that hold together adjacent water molecules are hydrogen bonds. Hydrogen bonds are the strongest type of intermolecular forces, but it is still relatively weak compared to ionic and covalent bonds. Hydrogen bonds occur because of the large difference between hydrogen atoms and the highly electronegative atoms such as F, N and O.
Covalent Bonds form large biological molecules
Hydrogen bonds are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.
ANSWER: nonpolar cavalent bonds and polar covalent bonds
Hydrogen bonds are considered weak bonds, however in large biochemical molecules, they can act as a stabilizer. An example is a protein, which contains numerous weak bonds (Hydrogen, van der Waals, and hydrophobic), after the primary structure.

C-H bonds
The stability of the three-dimensional shape of many large molecules is dependent on Hydrogen Bonds.
Intermolecular force holds large numbers of different molecules together.
Most Biological molecules are put together or held together by covalent bonds. Covalent bonds form between two nonmetal elements.
Hydrogen bonds. Collectively, they are strong enough to stabilize the characteristic structures of large biological molecules such as DNA. From the college text book "Biology: Concepts and Applications without Physiology 8th Edition".
