Biomolecules (1)

• Biomolecules


  • Carbohydrates
  • Proteins
  • Lipids
  • Nucleic Acids
• Monomers


  Small molecules, mostly organic, that can join with other similar molecules to form very large molecules
• Biomolecules are any molecules that are produced by a living organism, including large macromolecules
• Major categories of biomolecules

  • Carbohydrates
  • Proteins
  • Lipids
  • Nucleic Acids
• Carbohydrates


  Energy-giving molecules, made up of Carbon, Hydrogen, and Oxygen
• Carbohydrates


  • Monosaccharides are linked together by glycosidic bonds to form disaccharides or polysaccharides
  • Monosaccharides: Glucose, Fructose, Galactose
  • Disaccharides: Maltose, Lactose, Sucrose
  • Polysaccharides: Glycogen, Starch, Cellulose, Chitin
• Proteins


  Body-building molecules, made up of Carbon, Hydrogen, Oxygen, & Nitrogen
• Proteins


  • Monomers are Amino Acids
  • Amino Acids are linked by peptide bonds to form proteins
  • Examples: Amylase, Lipase, Keratin, Collagen
• Lipids and Nucleic Acids are also major categories of biomolecules
