Study Notes
Overview of Biochemistry
- Biochemistry studies chemical substances in living organisms and their interactions.
- It encompasses discoveries about how cells create essential life molecules and maintain chemical reactions.
Major Types of Biochemical Substances
-
Bioinorganic Substances:
- Do not contain carbon.
- Includes water and inorganic salts.
-
Bioorganic Substances:
- Contain carbon.
- Comprises carbohydrates, proteins, lipids, and nucleic acids.
Composition of the Human Body
- Water accounts for approximately 70% of human body mass.
- Proteins contribute around 15% of body mass.
- Inorganic salts make up about 5% of body mass.
- Lipids constitute roughly 8% of the body mass.
- Carbohydrates and nucleic acids each represent about 2%.
Importance of Biochemical Interactions
- Despite a predominance of organic substances, bioorganic molecules constitute only about one-fourth of body mass.
- Bioinorganic substances, especially water, are critical for sustaining life.
- Isolated biochemical substances are lifeless; however, their interactions within cells support life processes.
