• polysaccharide
• polyester
• polynucleotide

Why is folding so important in proteins?

• It gives them a unique, 3-D 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

Which of the following give a protein its unique 3-D shape? (3)

• the unique sequence of amino acids in the primary structure

• hydrogen bonding to form alpha-helixes and beta-pleated sheets in the secondary structure.

• unique interactions between the 'R' groups in the tertiary structure

• random folding due to temperature and extreme pH throughout the folding process

• unique sequence of monosaccharides in the quaternary structure
