tertiary structure and function of a protein

Question 1

What is tertiary structure Further conformational change of the secondary structure leads to additional bonds forming between the

Answer 1

R groups (side chains)

Question 2

The additional bonds are

Answer 2

Hydrogen (these are between R groups)

Disulphide (only occurs between
cysteine amino acids)

Ionic (occurs between charged R groups)

Weak hydrophobic interactions (between non-polar R groups)

Question 3

This structure is common in

Answer 3

globular proteins
