Protein Structure and Folding

If a hydrophobic amino acid sequence is placed in water the amino acids will

• fold in half
• unfold
• bunch up
• spread out

The level of protein structure that results from hydrogen bonding causing the protein to fold into α-helix and β-pleated sheets is known as

• primary structure
• secondary structure
• tertiary structure
• quaternary structure
