Monomers polymers and monosaccharides

• What are the two main types of molecules discussed?

  Monomers and polymers
• What is the definition of a monomer?

  Smaller units that create larger molecules
• What does the term "polymer" mean?

  Many monomers bonded together
• What is a key monomer discussed in carbohydrates?

  Glucose
• What are the three elements that carbohydrates contain?

  Carbon, hydrogen, and oxygen
• How are carbohydrates classified based on their units?

  • Monosaccharides: one unit
  • Disaccharides: two units
  • Polysaccharides: many units
• What are the disaccharides mentioned for the next lesson?

  Sucrose, maltose, and lactose
• What are the polysaccharides that need to be known?

  Starch, cellulose, and glycogen
• What is the molecular formula of glucose?

  C$_6$H$_{12}$O$_6$
• How many carbons are in the hexagon of glucose?

  Five carbons in the hexagon
• What is an isomer?

  Molecules with the same molecular formula but different structures
• What is the key difference between alpha and beta glucose?

  Position of hydrogen and hydroxy on carbon one
• What are the key points about glucose as a monosaccharide?

  • Key monosaccharide in carbohydrates
  • Exists as two isomers: alpha and beta
  • Molecular formula: C$_6$H$_{12}$O$_6$
• What should students do if the lesson is too fast?

  Pause the video and take notes
• What is the purpose of numbering the carbons in glucose?

  To describe their position easily
• How does the structure of alpha glucose differ from beta glucose?

  Hydroxy and hydrogen positions are swapped
