Study Notes
Macromolecules Overview
- Macromolecules consist of four main types: proteins, nucleic acids, carbohydrates, and lipids.
- They are essential for carrying out various biological functions.
Lipids
- Store energy, provide insulation, and form cell membranes.
- Long-term energy storage is achieved through lipids.
- Common examples include fats, oils, and cholesterol.
- Building blocks are fatty acids and glycerol.
Carbohydrates
- Function primarily to store energy in the short term.
- Constructed from simple sugars known as monosaccharides.
- Composed of carbon, hydrogen, and oxygen.
- Complex and simple sugars make up carbohydrates.
- Suffix "-ose" is typical for carbohydrate names.
Proteins
- Functions include building tissues, transporting molecules, and speeding up chemical reactions as enzymes.
- One role not associated with proteins is insulation.
- Building blocks of proteins are amino acids.
Nucleic Acids
- Primarily responsible for storing and transmitting genetic information.
- Examples include DNA and RNA.
- Monomers of nucleic acids are nucleotides.
- Composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
Additional Concepts
- Cellulose forms the cell wall of plants.
- The analogy "subunit is to macromolecules like brick is to building" illustrates how macromolecules are made of smaller units.
- Carbon is an excellent atomic backbone for macromolecules due to its four valence electrons, allowing it to form stable bonds with various elements.
