Weak bonds may be easily broken but they are very important because they help to determine and stabilize the shapes of biological molecules. For example, they are important in stabilizing the secondary structure (alpha helix and beta-pleated sheet) of proteins. Hydrogen bonds keep complementary strands of DNA together.

Why are weak bonds important in cells?
These weak bonds keep the DNA stable, but also allow it to be opened up for copying and use by the cell. More generally, bonds between ions, water molecules, and polar molecules are constantly forming and breaking in the watery environment of a cell.
What are the weak bonds that are important in chemistry life?
Hydrogen Bonds However, not all bonds are ionic or covalent bonds. Weaker bonds can also form between molecules. Two weak bonds that occur frequently are hydrogen bonds and van der Waals interactions. Without these two types of bonds, life as we know it would not exist.
What is a key biochemical advantage of the use of weak bonds in biochemistry?
Why are weak bonds important in biochemistry? Many weak bonds allow for highly specific yet transient interactions.
Why are weak bonds important for macromolecules?
Crucial role of weak attractions in macromolecules: Weak attractions are crucial to macromolecular structure and functions because all the non covalent interactions such as hydrophobic attractions, ionic attractions and van-der Waals attractions are much weaker than that of the covalent attractions.
Why is it important for living organisms to have both strong bonds and weak bonds?
It is important to have both strong and weak bonds because small molecules need weak bonds to form strong bonds. Most ionic compounds are crystalline at room temperature and have higher melting points than molecular compounds formed by covalent bonds.
What is the importance of hydrogen bonds in biological systems?
Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.
What is a weak bond called?
Hydrogen Bonds and Van Der Waals Interactions. Hydrogen bonds are known as weak bonds because under normal biological conditions, they are easily and quickly produced and broken. Of all intermolecular attractions between molecules, Van der Waals interaction is the worst.
How do weak bonds hold large macromolecules together?
Boston: Jones and Bartlett, 1992. A macromolecular chain is held together by covalent bonds, which are strong enough to preserve the sequence of subunits for long periods of time. These weak bonds form between different parts of the same macromolecule and between different macromolecules.
Which statement about weak bonds is correct mastering biology?
Which statement about weak bonds is correct? Weak bonds are transient and easily reversible. Molecules that form weak bonds can come together, interact, and then separate. The combined effect of many weak and transient hydrogen bonds or Van der Waals interactions can produce important emergent properties.
How are weak interactions advantageous to an organism?
How are weak interactions such as these advantageous to an organism? They break and provide energy for covalent interactions.
What is the most important chemical bond?
Covalent Bonds. Another type of strong chemical bond between two or more atoms is a covalent bond. These bonds form when an electron is shared between two elements and are the strongest and most common form of chemical bond in living organisms.
What is weak interactions in chemistry?
Introduction. In structural chemistry and crystallography, the term ‘weak interactions’ usually brackets together everything weaker than a single covalent bond or an electrostatic interaction between directly contacting fully charged ions of opposite sign (i.e. an ionic bond).
