Exam Tip

You will be expected to recognise whether an unfamiliar molecule is an amino acid or

protein so look for the functional groups (amine and carboxyl). When asked to identify the

location of the peptide bond, look for where nitrogen is bonded to a carbon which has a

double bond with an oxygen atom, note the R group is not involved in the formation of a

peptide bond.
