A quick source of energy!! Carbohydrates A quick source of energy!!

What elements are carbs composed of? Carbon (C), Hydrogen (H) and Oxygen(O) In a ratio of – C : H : O 1 : 2 : 1 Example: Glucose C6H12O6 6 For every 1 Carbon (C) You will have 2 Hydrogens (H) and 1 Oxygen (O).

Carbohydrate Monomers (Building Blocks) Monosaccharides: are simple sugars commonly found in rings. Mono=one, Saccharide=sugar

Carbohydrate Monomers (Building Blocks) Monosaccharides Examples: Glucose: commonly found in blood of animals Galactose: a simple sugar found in milk Fructose: commonly found in fruit

Carbohydrate Monomers (Building Blocks) Glucose

Carbohydrate Polymers Polysaccharides: Poly=Many, Saccharide=sugar Polysaccharides are made by linking monosaccharides together. They can be very large and complex.

Carbohydrate Polymers Disaccharides: Di=Two, Saccharide=sugar Disaccharides contain 2 monosaccharides joined by dehydration synthesis.

Carbohydrate Polymers Dissacharide Examples: 2. Sucrose: “Table Sugar” Made up of Fructose + Glucose 1. Lactose: Found in Milk Made up of Galactose + Glucose 8

Carbohydrate Polymers Complex Carb (Larger polysaccharide) examples 1. Starch: a form of glucose in plants (breads, pasta, potatoes)

Carbohydrate Polymers Complex Carb (Larger polysaccharide) examples 2. Cellulose: contained in the cell walls of plants; gives strength and rigidity to plant cells.

Carbohydrate Polymers Complex Carb (Larger polysaccharide) examples 3. Glycogen: a common storage form of glucose in animals (stored in the muscles and liver to be used as quick energy)
