Mod 4

• Biomolecules


  Biological molecules produced by cells and living organisms, with a wide range of sizes, structures, and functions
• Major types of biomolecules


  • Carbohydrates
  • Lipids
  • Nucleic acids
  • Proteins
• Monomers


  Building blocks of biomolecules, e.g. monosaccharides, fatty acids, amino acids, nucleotides
• Biomolecules


  • Significant for many bodily functions
  • Play an important role in biochemical reactions of the human body
• Activity 1: Guess the Word


  Identify the type of biomolecule based on given pictures

  
• Carbohydrates


  Food sources: Pastas, breads, fruits, vegetables
• Proteins


  Food sources: Seafoods, milk, eggs, cheese
• Lipids


  Food sources: Nuts, oils, butter, fats
• Nucleic acids


  Food sources: DNA, RNA
• Activity 2: What's My Composition!

  Identify the elemental composition of biomolecule structures

  
• Elements present in all biomolecules: carbon, hydrogen, oxygen
• Similarities between proteins and nucleic acids: both contain nitrogen
• Element only present in nucleic acids: phosphorus
• Life is "carbon-based", with carbon atoms forming the fundamental components of many molecules in living things
• Activity 3: You Complete Me!

  Fill in information about biomolecules based on their structure, elements, monomers, functions, and food sources
• Biomolecules are considered organic because they are carbon-based compounds found in living organisms
• Activity 4: Think About Me!
