  1. Energy Storage & Use Unit 7 Section B

  2. Carbohydrates • Glucose – Key energy releaser • 2:1 ratio H to C • Monosaccharide – Simple sugar • 5 to 6 Carbon atoms • Glucose – Ring form mostly

  3. Carboeg. → Sugar, Starch, Cellulose. • Disaccharide → Glucose+Fructose= Sucrose • Polysaccharide → STARCH Grains & Vegetables • Eg.. CELLULOSE- woody fibers plants

  4. STARCH – Easy to digest • Cellulose- Indigestible to humans • Fibers→ Indigestible carbohydrates Carbos/Fats → High Energy Storage 1 gram Carbohydrates = 4 Calories 1 gram Fats = 9 Calories

  5. Nutritionists – 45-65% Calories • Glycogen → Meats • U.S. Pop. → Carb source – Wheat based sources • 145 lb. sugar / year

  6. FATS – Negative meaning • Meats, Oils, Dairy, Nuts, Grains • “Triglyceride” = “Fats” • Fewer O2 atoms / More C-H Bonds • Fats are NONPOLAR. • Soluability in water?????

  7. FATTY ACID → Long H-C chain w/COOH on the end • COOH – Carboxylic Acid • Stored Energy→Fats>Carbohydrates

  8. Saturated Fats – Single C bonds • Unsaturated Fats – • Double or Triple bonds • Monounsaturated – 1 double bond • Polyunsaturated – 2+ C=C bonds • Fish, Nuts, Legumes

  9. Unsaturated Fats → More Chemically reactive. • Saturated Fats → Contribute to Health problems.
