    Study Notes

    Chapter 6: Proteomics and Metabolomics

    • Proteomics is the study of proteins
    • Metabolomics is the study of metabolites
    • Proteomics examines the proteins within an organism, and their changes over time. Proteins vary from cell to cell over time
    • Metabolomics examines the molecules involved in metabolism, such as sugars, lipids, amino acids, fatty acids, phenolic compounds and alkaloids. These molecules interact and change constantly
    • Proteomics involves methods of measurement using NMR and FTIR spectroscopy
    • Metabolomics involves studying substrates and products of metabolism affected by both genetic and environmental factors.
    • Proteomics can aid in bioinformatics, agriculture, protein interaction studies, biomarker identification, protein structure characterization, brain cell structure analysis at molecular level, and neurotoxicology studies.
    • Proteomic methods like 2D-PAGE and SDS-PAGE enable the separation of proteins.
    • Proteomics and metabolomics aid in pharmaceutical development, preventative healthcare, improving crop genetics, and customized treatment.
    • There are methods of measurement used to determine the products of reactions, including NMR (Nuclear Magnetic Resonance) and FTIR (Fourier Transform Infrared) Spectroscopy.
