Study Notes
Introduction to Biochemistry
- Coined in 1903 by Carl Neuberg, who is considered the father of modern biochemistry.
- Neuberg's contributions include discovery of carboxylase and elucidating alcoholic fermentation as a series of enzymatic processes.
- Biochemistry studies chemical substances in living organisms and their interactions.
Principal Areas of Biochemistry
- Structural Biochemistry: Investigates the relationship between the molecular structure of biochemical substances and their biological functions.
- Metabolism: Examines all chemical reactions occurring in living organisms.
- Molecular Genetics: Focuses on the chemistry behind processes that store and transmit biological information, aiming to understand heredity and genetic expression.
Characteristics of Living Organisms
- High chemical complexity and microscopic organization.
- Biological structures have functional purposes.
- Active energy transformations are ongoing within living systems.
- Capacity for self-replication is inherent in living organisms.
- Mechanisms present for sensing and responding to environmental changes.
- Evolutionary changes are documented across living systems.
Applications of Biochemistry
-
Medicine:
- Physiology: Understands biochemical changes related to physiological alterations.
- Pathology: Assists physicians in diagnosing disorders based on symptoms.
- Hormonal Deficiency: Addresses disorders caused by hormonal imbalances.
-
Nursing:
- Kidney function tests gauge drug excretion levels.
- Liver function tests identify liver damage.
- Blood tests measure glucose levels for diabetes severity.
- Serum cholesterol tests assess cardiovascular disease risk.
-
Agriculture:
- Facilitates disease prevention and treatment, enhancing crop yield and quality.
- Informs fertilizer usage to boost plant growth.
-
Nutrition:
- Analyzes food components such as carbohydrates, proteins, and fats.
- Highlights the significance of vitamins, minerals, and essential fatty acids for health.
-
Pharmacy:
- Biochemical tests determine the half-life and expiry dates of drugs.
- Explains how drug molecules are metabolized through biochemical reactions.
Cellular Biology
- Cells are the smallest living units capable of performing life functions, observed only under a microscope.
-
Types of Cells:
-
Prokaryotic Cells:
- Organisms are called prokaryotes, primarily bacteria.
- Lacks a nucleus; has less defined structures.
- Contains cell wall, outer membrane, and plasma membrane for material regulation.
-
Eukaryotic Cells:
- Organisms known as eukaryotes, including animals, plants, fungi, and protists.
- Characterized by the presence of a nucleus and various membrane-bound organelles.
