Study Notes
Macromolecules Overview
- Four primary macromolecules: Nucleic Acids, Proteins, Carbohydrates, Lipids.
- These macromolecules are essential for various biological functions and structures.
Nucleic Acids
- Composed of nucleotides, which are the monomers.
- Phosphodiester bonds connect nucleotides, forming the sugar-phosphate backbone of DNA and RNA.
Proteins
- Made up of amino acids, which serve as the monomers.
- Peptide bonds link amino acids together, facilitating protein structure and function.
Carbohydrates
- Monosaccharides, such as glucose, are the basic units (monomers).
- Glycosidic bonds connect monosaccharides to form disaccharides and polysaccharides, which serve as energy sources and structural components.
Lipids
- Composed of Glycerol and Fatty acids as building blocks; do not have a clear monomer structure.
- Ester bonds, a type of covalent bond, link glycerol with fatty acids, forming triglycerides and other lipid structures.
Symbiotic Relationships
- Three main types of symbiosis:
- Mutualism: Both species benefit from the interaction.
- Commensalism: One species benefits while the other is neither helped nor harmed.
- Parasitism: One species benefits at the expense of the other.
Examples of Symbiotic Relationships
- Trichonympha and Termites: Mutualistic relationship where Trichonympha aids in digesting cellulose in wood for termites.
- E.coli and Humans: Commensal relationship; E.coli helps in digestion without harming the human host.
