Answer 3

-occur when 2 monosaccharide molecules are joined together by a dehydration reaction
- many have polar functional groups; therefore hydrophilic

Answer 4

• long chains and are polymers of monosaccharides
• main function is for energy storage and structure support
• polar and very hydrophilic
