State the letter, A to D, of the molecule in Fig. 1.1 that can make peptide bonds.
State the letter, A to D, of the molecule in Fig. 1.1 that has ester bonds.
Some molecules in Fig. 1.1 are able to form polymers. Name one polymer that can be formed only from many molecules of C.
State one visible difference in Fig. 1.1 between the part labelled 1 of molecule A and the part labelled 2.
Molecule D can make macromolecules with other similar monomers. The three-dimensional shapes of these macromolecules are held together by interactions or bonds other than those between adjacent monomers. Name two of these interactions or bonds.
