Explain what the term primary structure means.
The molecular structure of the first two amino acids in lysozyme, lysine and valine, is shown. Use the space provided to show how these amino acids are joined in a condensation reaction.
Describe the secondary and tertiary structure of an enzymatic protein, for example lysozyme. secondary … tertiary …
State why enzymes, such as lysozyme, need a tertiary structure.
A rare disease is caused by a single change in the DNA nucleotide sequence of the gene that codes for lysozyme. This change produces an insoluble protein with a different structure from the normal soluble lysozyme molecule. Suggest how a change in the gene can explain the differences observed between the normal lysozyme and the altered lysozyme.
