Macromolecules Overview

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.
