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 C 6 H 12 O 6

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? – C 6 H 12 O 6

Carbohydrates – 3 types Disaccharides – 2 monosaccharides linked together – Dehydration synthesis Predict the molecular formula for a disaccharide. – C 12 H 22 O 11

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 term E storage – Branched chain – animals
