rotein structure and what type of bond is primarily responsible for each level?

What is the primary structure of a protein? What is the importance of the primary structure?

a helix and B pleated sheets are what protein structure? primary, tertiary, secondary, or quaternary?

Protein structures have several different levels of organization. In the space below indicate the type of molecular bonds that can contribute to each level of organization: primary-  secondary- tertiary- quarternary-

What level of protein structure refers to corkscrews or sheets formed due to hydrogen bonding within a single polypeptide?

How do secondary and tertiary structures of proteins differ?

A mutation leads to a change in amino acid from valine, an amino acid with a nonpolar side chain, to aspartic acid, an amino acid with a polar, negatively-charged side chain. Do you think that the following levels of protein structure change? If so, how and why? If not, why not? Please frame your answer in terms of chemical bonds and interactions. (primary structure, secondary structure, tertiary structure, quartenary structure)
