Study Notes
Role of Biochemistry in Biomedical Engineering
- Biomedical engineers analyze complex systems to understand their smallest functional units and interactions.
- Biochemistry studies chemical processes within living organisms, essential for understanding health and disease.
- A fundamental knowledge of biochemistry is crucial for diagnosing and addressing biomedical problems effectively.
- Key biomedical engineering fields that utilize biochemistry include:
- Tissue Engineering: Designs functional replacement tissues and organs using biochemical principles.
- Biopharmaceutical Engineering and Drug Delivery: Focuses on drug properties and interactions with biological systems for targeted delivery.
- Medical Imaging (Radiology): Involves the design of imaging techniques based on the properties of contrast agents to visualize cellular processes.
- Biomechanics: Examines and utilizes the mechanical properties of biological materials in medical device development.
- Gene Therapy: Seeks to treat genetic disorders by correcting DNA issues; clinical biochemists assess the effects of gene therapies on diseases.
Overview of the Periodic Table
- Elements are arranged in order of atomic number, with similar properties grouped in vertical columns (groups).
- The table features seven horizontal rows (periods) and 18 vertical columns, with lanthanides and actinides displayed below the main table.
- Periodic Law: Properties of elements are periodic functions of their atomic numbers; differences and similarities exist among elements.
- Elements are categorized into:
- Metals: Shiny, malleable, and good conductors of heat and electricity.
- Nonmetals: Dull appearance, poor conductors of heat and electricity.
- Metalloids: Moderate conductors with properties of both metals and nonmetals.
- Main classifications include:
- Main-Group Elements: Columns labeled 1, 2, and 13–18.
- Transition Metals: Columns labeled 3–12.
- Inner Transition Metals: Lanthanides (top row) and actinides (bottom row).
- Specific groups within the periodic table include:
- Alkali metals (Group 1)
- Alkaline earth metals (Group 2)
- Pnictogens (Group 15)
- Chalcogens (Group 16)
- Halogens (Group 17)
- Noble gases (Group 18)
- Unique characteristics of hydrogen: Nonmetallic element resembling both Group 1 and Group 17 properties.
- Elements with purely unstable radioactive isotopes (e.g., technetium, promethium, polonium) have atomic masses indicated in brackets, denoting the most stable isotope's approximate weight.
Characteristics of Metals and Nonmetals
- Majority of elements in the periodic table are classified as metals, reflecting their dominance in the table's structure.
