Study Notes
Biochemicals
- Carbon, hydrogen, oxygen, and nitrogen are essential elements present in all biochemicals.
Classification of Compounds
- Water and carbon dioxide are categorized as inorganic compounds because they do not contain carbon-hydrogen bonds.
Building Blocks of Complex Compounds
- Monosaccharides, fatty acids, amino acids, and nucleotides are the building blocks of carbohydrates, lipids, proteins, and nucleic acids, respectively.
Energy Resources
- Fossil fuels, such as coal, oil, and natural gas, are the long-term energy resources for humans.
Lipid Structure
- The main components of lipids are glycerol and fatty acids.
Fatty Acids
- Saturated fats have single bonds between carbon atoms, while unsaturated fats have one or more double bonds between carbon atoms.
Protein Function
- The function of a protein is determined by its specific shape and chemical properties.
Enzymes
- Enzymes are also called biological catalysts.
Temperature Effects on Enzymes
- High temperatures can denature enzymes, leading to a loss of their biological function.
Combining Organic Compounds
- Organic compounds can be combined through condensation reactions, which involve the loss of a water molecule.
Carbohydrate Structure
- The main components of carbohydrates are carbon, hydrogen, and oxygen atoms, typically in a ratio of 1:2:1.
