Study Notes
Macromolecules
- Large structures that make up all living organisms
- Composed of polymers, which are formed by binding multiple monomers together
Types of Macromolecules
- Categorized into four main groups: carbohydrates, lipids, proteins, and nucleic acids
Carbohydrates
- Primary function: main fuel source and structural support for plants
- Monomers: monosaccharides (e.g., glucose)
- Polymers: polysaccharides (long chains of monosaccharides)
- Example: glucose, an energy source for the body that produces ATP
Lipids
- Variety of functions: energy storage, membrane formation, and steroid function
- No monomers or polymers
- Characteristics: hydrophobic (water-repelling)
- Composed of: fats, phospholipids, and steroids
- Fats: can be saturated or unsaturated
- Phospholipids: form cellular membrane with hydrophobic tails and hydrophilic heads
- Steroids: regulate sex hormones
Proteins
- Crucial for all cellular functions
- Monomers: amino acids (20 different types)
- Polymers: polypeptides (function dependent on amino acid folding)
- Folding types: primary, secondary, tertiary, quaternary
Nucleic Acids
- Primary function: transmit and express genetic information
- Monomers: nucleotides (nitrogenous bases: A, T, C, G, U)
- Polymers: polynucleotides (strands of DNA and RNA)
