Q
Q: What type of interaction stabilizes the tertiary structure of proteins?
Solution: The tertiary structure of proteins is stabilized by a combination of hydrophobic interactions, ionic interactions, hydrogen bonds, and sometimes covalent bonds.
Steps: 8
Step 1: Understand that proteins are made of long chains of amino acids.
Step 2: Know that the tertiary structure is the overall 3D shape of a protein.
Step 3: Learn that this shape is important for the protein's function.
Step 4: Identify the types of interactions that help hold this shape together.
Step 5: Recognize that hydrophobic interactions occur when non-polar parts of amino acids avoid water and group together.
Step 6: Understand that ionic interactions happen between positively and negatively charged parts of amino acids.
Step 7: Realize that hydrogen bonds form between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
Step 8: Acknowledge that sometimes covalent bonds, like disulfide bridges, can also help stabilize the structure.
