Which of the following describes the secondary structure of proteins?

• The sequence of amino acids

• The α-helix and β-pleated sheet folding

• The folding of the polypeptide chain due to the 'R' groups

• The joining of different protein molecules to make one big molecule

Why is folding so important in proteins?

• It gives them a unique, functional shape

• It makes them look tidier

• It makes every protein molecule different from the next even if they are the same type

• The folding is random so is not that important at all
