Primary
specific chain of amino acids
depends on the order and number of amino acids
gives it, it's specific function
Stabilizing Factors
Peptide Bonds
secondary
alpha helix and beta pleated Sheet
twist around each other
Stabilizing Factors
Hydrogen Bonds in Between molecules
tertiary
Give enzymes their specific active site and shape
Stabilizing Factors
