Why do people eat a bowl of pasta before a race??? !

ORGANIC COMPOUND Carbohydrates

Carbohydrates Are needed for energy Cell walls (cellulose) “ose” endings Are made of C, H, O Have a 2:1 ratio of hydrogen to oxygen Sugars, starches, cellulose, glycogen

Types of Carbohydrates 1. Monosaccharides  simple sugars –Glucose –Galactose –Fructose Isomers!!! –C 6 H 12 O 6

Continue with Carbs… 2. Disaccharides  two monosaccharides together by dehydration synthesis –Maltose –Sucrose –Lactose C 12 H 22 O 11

Still More on Carbs… 3. polysaccharide  more than three monosaccharides combined 4. Polymers – starch, cellulose, SUPER LARGE CARBS!

Dehydration Synthesis of Carbohydrates!! Monosaccharide + monosaccharide  disaccharide + water

Condensation Reaction IS ANOTHER NAME FOR DEHYDRATION SYNTHESIS!!!!!!!!!!!!!!

Dehydration Synthesis Simplified!!

Samples of Monosaccharides *

Hydrolysis is the REVERSE of dehydration synthesis Add water to break carbohydrates down into their building blocks!
