    Study Notes

    Proteomics and Metabolomics

    • Proteomics is the study of proteins
    • It identifies the number of proteins in an organism, which can differ between cells over time.
    • Changes in protein numbers occur due to phosphorylation and glycosylation.
    • Protein changes can be indicators of cell development, differentiation, cell cycle, or carcinogenesis (biomarkers).

    Applications of Proteomics

    • Bioinformatics
    • Agriculture
    • Protein interaction
    • Biomarker
    • Protein structure
    • Characterization of brain cells at a molecular level
    • Neurotoxicology

    Metabolomics

    • Study of substrates and products of metabolism influenced by both genetic and environmental factors.
    • Molecules involved in metabolism include sugars, lipids, amino acids, fatty acids, phenolic compounds, and alkaloids.
    • Interactions between molecules rapidly change over time.
    • Molecules are continuously absorbed, synthesized, degraded, and interact with other molecules.

    Application of Metabolomics

    • Pharmaceuticals
    • Preventive healthcare
    • Agricultural industries (improving plant genetics)
    • Biomarker discovery (possible personalized treatment)
