Study Notes
Historical Milestones in Biochemistry
- 1990: Introduction of gene therapy.
- 1993: Kary B. Mullis invented the Polymerase Chain Reaction (PCR).
- 1990-2003: Human Genome Project aimed at mapping the human DNA sequence.
- 2012: Development of CRISPR-Cas9, a groundbreaking genome editing method.
- Soren Sorensen (1868-1939) introduced the concept of pH.
- James D. Watson and Francis Crick established the double helix structure of DNA.
- James B. Sumner (1887-1955) was the first to crystallize an enzyme, urease.
Nature of Biochemical Reactions
- Biochemical reactions transform one molecule into another within cells.
- These reactions are critical for metabolism, encompassing both catabolic and anabolic processes.
- Enzymes, as biological catalysts, mediate biochemical reactions, influencing their rate and specificity.
Importance of Biochemistry
- Biochemistry describes biological processes at the molecular level, including the organization and function of living matter.
- It plays a crucial role in understanding the chemical processes of living cells, metabolism, and regulation.
- Biochemical research underpins advancements in medicine, agriculture, and biotechnology, addressing metabolic diseases and enhancing productivity.
Omics Fields in Biochemistry
- "Omics" refers to a comprehensive study of large biological data sets.
- Genomics studies genes and their functions.
- Proteomics explores the structure and functions of proteins.
- Transcriptomics examines RNA molecules.
- Lipidomics focuses on lipid structures and functions.
- Metabolomics analyzes metabolic profiles in organisms.
- Nutrigenomics investigates how nutrition interacts with genes.
- Pharmacogenomics studies how genes affect individual responses to medications.
Key Biochemical Reactions
- Neutralization Reactions: Involves the reaction of an acid and a base producing water and salt.
- Oxidation-Reduction Reactions: Involves the loss (oxidation) and gain (reduction) of electrons.
- Condensation Reactions: Combine two molecules to create a single larger molecule, often forming covalent bonds (e.g., between amino acids).
- Hydrolysis Reactions: Utilize water to break down polymers into monomers, releasing energy.
- Phosphorylation: Involves adding a phosphate group to molecules, essential for energy transfer in cells.
- Decarboxylation: Removes a carboxyl group and releases carbon dioxide, often occurring with carboxylic acids.
Applications of Biochemistry
- Biochemical understanding is essential for addressing health and disease, as most diseases have biochemical underpinnings.
- Disturbances in biochemical processes can lead to health issues like hormonal imbalances, electrolyte imbalances, and genetic disorders.
- Research in genetics, cell biology, immunology, nutrition, pharmacology, and pathology is vital for advancing biochemistry and improving health outcomes.
Fun Fact
- The human brain conducts over 100,000 biochemical reactions every second.
