Review Questions

• How does mass spectrometry enhance our understanding of parasite biology?
  • Mass spectrometry enhances our understanding of parasite biology by allowing researchers to analyze the molecular composition of parasites and their interactions with hosts. By identifying proteins and metabolites present in parasites, scientists can uncover important details about their life cycles, pathogenicity, and how they evade host immune responses. This information is crucial for developing targeted treatments and vaccines against parasitic diseases.
• Discuss the role of ionization in the process of mass spectrometry and its importance for analyzing biological samples.
  • Ionization is a fundamental step in mass spectrometry where molecules are converted into ions. This process is crucial because only ions can be manipulated by electric and magnetic fields, allowing them to be separated based on their mass-to-charge ratios. For biological samples, effective ionization techniques, such as electrospray ionization or matrix-assisted laser desorption/ionization, ensure that the diverse range of biomolecules, including proteins from parasites, can be accurately analyzed for their composition and function.
