Study Notes

Biochemistry Lecture 1: Introduction

  • Biochemistry is the study of chemical substances and interactions in living organisms.
  • It includes chemical reactions, catalysts, and metabolic processes.
  • It's crucial for developing medical and cleaning products, and DNA technologies.

Branches of Biochemistry

  • Medical Biochemistry: Focuses on the functioning of organisms, both normal and diseased, and laboratory management in healthcare.
  • Clinical Biochemistry: Deals with analyzing and interpreting chemical tests to diagnose and treat patients.
  • Pharmaceutical Biochemistry: Examines how drugs affect biological systems, including human health and illness. This also covers drug delivery, enzymology, pharmacokinetics, pharmacodynamics, and pharmacology.

Biographical Importance

  • Biochem is vital to comprehending the interplay between molecules and diseases.
  • Understanding mechanisms of disease allows for targeted treatments.
  • Testing and assessment of disease progression and response to treatments is important.

The Cell (General Structure)

  • Cells: The fundamental units of biological activity.
  • Prokaryotes: Lack a defined nucleus (e.g., bacteria).
  • Eukaryotes: Contain a defined nucleus (e.g., animals, plants).
  • The Cell's Parts: Plasma membrane (separates internal & external environments), Cytoplasm (holds internal components), nucleus (contains most of the cell's DNA)

Biomolecules

  • Proteins: Fundamental building blocks and function of cells. They are made up of amino acids.
  • Nucleic Acids: Polymer molecules whose repeating units are nucleotides. DNA (stores genetic info); RNA (required for protein synthesis).
  • Carbohydrates: Short-term energy source, stored long-term energy, structural components of membranes.
  • Lipids: Long-term energy storage and structural components of membranes.
  • Bio-inorganic substances: Substances that lack carbon in their composition, including water and salts.

Applications of Biochemical Testing

  • Disease Diagnosis: Identifying and assessing the nature and mechanisms of diseases.
  • Treatment Decisions: Determining appropriate treatments based on the fundamental causes.
  • Disease Monitoring: Evaluating disease progression and treatment response.
  • Prenatal Diagnosis: Screening for diseases early through prenatal testing.
  • Newborn Screening: Detects congenital issues in newborns through biochemical analysis.

Key Terms

  • Polymer: A large molecule formed by repeating smaller molecules (monomers).
  • Monomer: The smaller molecules that make up a polymer.
  • Drugs: Chemical substances used to treat diseases, diseases affect living organisms and their chemical processes.
  • Atorvastatin: A medicine for hypercholesterolemia (high cholesterol).
  • Enzymes: Biological catalysts that speed up reactions in living organisms.
  • Pharmacokinetics: Study of how drugs are absorbed, distributed, metabolized, and excreted.
  • Pharmacodynamics: Study of how drugs affect biological systems.
