• What are the functions of carbohydrates?

  Energy storage

  Structural support

  Specialised roles when modified with other macromolecules
• The three main types of carbohydrates are monosaccharides (simple sugars), disaccharides (double sugars), and polysaccharides (complex sugars).

  Multiple
• Are monosaccharides water soluble. True or false?

  True
• What two categories of sugar are monosaccharides split into?

  Aldose and ketose sugars
• In monosaccharies, what is their distinctive structure?

  1. carbon skeleton with 3 or more carbon atoms
  2. each carbon atom except one has an OH group
  3. one carbon atom has a carbonyl group
