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

The main bonding in the secondary structure of a protein is due to.....

• covalent bonding

• ionic bonding

• hydrogen bonding

• polar bonding

What is a peptide bond?

• Bond that holds two amino acids together.
• A bond that holds hydrogen and oxygen molecules together.
• A bond that holds the phosphate group of one nucleotide and a sugar of a neighboring nucleotide.
• A bond that is formed by the sharing of electrons.
