Study Notes
Introduction to Biochemistry
- Biochemistry combines biology and chemistry to study living matter.
- It investigates the chemical substances and processes that occur in living organisms such as plants, animals, and microorganisms.
- It plays a crucial role in various fields including medicine, nutrition, genetics, and agriculture.
Organic and Inorganic Molecules
- There are two main types of molecules needed for life processes: organic and inorganic.
- Organic molecules contain carbon and hydrogen atoms.
- Inorganic molecules do not contain carbon.
Macromolecules
- Macromolecules are large organic molecules essential for living organisms.
- The major classes of macromolecules include carbohydrates, lipids, nucleic acids, and proteins.
Carbohydrates
- Carbohydrates are made up of carbon, hydrogen, and oxygen.
- They serve as energy storage and structural components.
- Examples include sugars, starches, cellulose, and glycogen.
- Polysaccharides are large carbohydrates composed of chains of monosaccharides.
Lipids
- Lipids are made up of carbon, hydrogen, and oxygen.
- Lipids include fats, oils, hormones, and vitamins.
- They serve as energy storage and contribute to cell membrane structure.
- Lipids are built from fatty acids and glycerol.
Nucleic Acids
- Nucleic acids are made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
- They are polymers of nucleotides.
- DNA and RNA are examples of nucleic acids.
