Lets Carb Up!!!
Carbohydrates - Composition
• Made of… (Hint: look at the name)– Carbon– Hydrogen– Oxygen
Carbohydrates - 3 Types
• Monosaccharides– These are the monomer units– Means 1 sugar or simple sugar– Ring Shaped molecules– Provide quick energy for cells
• C6H12O6
Monosaccharide examples
• Glucose
• Fructose
• Galactose
Isomers
• Isomers-have the same molecular formula, but different structural formulas
• Glucose, Galactose and Fructose all have the same molecular formula…what is it?– C6H12O6
Carbohydrates – 3 types
• Disaccharides– 2 monosaccharides linked together
– Dehydration synthesis
• Predict the molecular formula for a disaccharide.– C12H22O11
Disaccharides - examples
• Sucrose– Glucose and fructose
• Maltose– 2 glucose
• Lactose– Glucose and galactose
Carbohydrates – 3 Types
• Polysaccharides– Many monosaccharides linked together
– Dehydration Synthesis
• Polymers
Carbohydrates - Uses
• Used by cells to store and release energy
• Used to make cell structures
Structural Carbs• Polysaccharides-built from the monomer glucose• Cellulose– Structural– Chain-link fence– Plants
• Chitin– Structural– Animals
Energy Storage
• Simple Sugars– Quick release E– Mono and di’s
Polysaccharides• Starch
– Long term E storage– Straight chain– plants
• Glycogen– Long termE storage– Branched chain– animals
