Proteins: Interactions & Shape

Question 1

A polypeptide chain will fold differently due to the interactions (and hence the bonds that form) between

Answer 1

between R groups. The three-dimensional configuration that forms is called the tertiary structure of a protein

Question 2

Each of the twenty amino acids that make up proteins has a unique …… group and

therefore many different interactions can occur creating a vast range of protein configurations and therefore ………..

Answer 2

R

interactions

functions

Question 3

Within tertiary structured proteins are the following bonds:

Answer 3

Strong covalent disulfide

Weak hydrophobic interactions

Weak hydrogen

Ionic
