Structure of Glucose
Molecular Formula for Glucose?
Structure of Fructose?
Molecular formula for Fructose?
What is a disaccharide?
2 monomers put together
What is the disaccharide sucrose made from?
Fructose and Glucose -
What is the Disaccharide Lactose made from?
Galactose + Glucose
Why do Fructose and Glucose act differently despite having the same molecular formula?
Because the molecules are arranged differently (Fructose has 2 external carbons; Glucose has 1 external carbon)
A polymer consisting of amino acid monomers covalently bonded together
Example of a polysaccharide
Functions of Polysaccharides
Energy storage molecules
Equation for Condensation Synthesis and Hydrolysis?
O ⇌ H
Removal Water - To join monomers e.g. fructose and glucose to make sucrose
Addition of water - To break apart polymers into monomers
Molecular Formula for Carbohydrates?
Where are Polysaccharides stored?
Chloroplasts where light energy is collected and where photosynthesis takes place. During photosynthesis starch id hydrolised into glucose for energy.
2 types of glucose?
Alpha and Beta
What type of glucose is cellulose made from?
What does Beta Glucose look like?
What does alpha glucose look like?
How beta glucose joins to form cellulose?
What is the name of the covalent bond formed in a condensation reaction?
