Enzymes & the digestive system - Carbohydrates - monosaccharides

Question 1

monosaccharides

Answer 1

glucose
fructose
galactose
- soluble substances
- single sugars
- general formula - (CH2OH)n
- structure of it makes it white crystaline
- monomer untis for carbohydrates

Question 2

disaccharides

Answer 2

• two monosaccharides joined with glycosidic bond
• glucose + glucose = maltose
  glucose + fructose = lactose
  glucose + galactose = sucrose

Question 3

what happens at a condensation reaction?

Answer 3

• molecule of water removed
• 2 monosaccharides join
• ## new bond formed = glycosidic

Question 4

what happens at hydrolysis ?

Answer 4

the addition of water that causes breakdown

• water added to disaccharide under suitable conditions
• glycosidic bond broken
• releases constituent monosaccharides
