Question 6

Primary protein structure

Answer 6

Many amino acids linked in a chain via peptide bonds

Question 7

Disulphide bridges

Answer 7

Strong bonds between the 2 sulfur molecules on the 2 cystine amino acids - can be in either primary or tertiary protein structure

Question 8

Secondary structure of proteins

Answer 8

This consists of hydrogen bonds between lone pair of electrons on oxygen and Hydrogen attached to Nitrogen between adjacent chains. This allows it to form an alpha helix of beta pleated sheet shape
