secondary level
|
looks at the patterns of folds of protein
|
|
|
alpha-helix
|
polypeptide in coiled position
stabalized by H bonds |
|
|
Beta-sheets
|
polypeptide lays side by side with other polypeptides or folds to create a layered appearance

|
|
chaperones
|
proteins that help other proteins to fold tertiary level correctly
|
|
|
quarternary level
