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
Methods of Measurement

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)
Proteomics and Drug Discovery
- Target identification and selection.
- Target isolation and purification.
- Structure determination.
- Analysis of structure for potential ligand binding sites.
- Docking of small molecules using computational methods.
- Biochemical assays and further testing.
- Lead optimization to improve potency.
- Cytotoxicity tests, pharmacokinetic studies, and toxicological investigations.
