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
