P p carbohydrates wnotes #4 Presentation Transcript

  • 1. General Biology – Biochemistry Carbon Compounds Section 2.3
  • 2. A Little Review… Elements, M M Organic A atoms Molecules A compounds Protons K & KNuetrons E M E Compoundselectrons A U K U P E P U p The Basic Unit of Life cells
  • 3. Inorganic vs Organic•Non-living •Produced by living•Do not contain thingscarbon (exceptions) •All contain carbon•Needed for life •Important organic•Plants organize compoundsinorganic compounds –Carbohydratesinto organic –Lipids•H2O, O2, CO2 –Proteins•Minerals, nitrates –Nucleic acids
  • 4. What is the big deal about carbon??Carbon is very versatileIt can form 4 covalent bonds
  • 5. Where does all of the carbon for living things come from?Organic Molecule
  • 6. CARBOHYDRATES
  • 7. Carbohydrates Needed for short term energy storage (cell fuel) and structural support Made of C, H, O (1:2:1) Building blocks (monomers) are simple sugars C6H12O6 Big– Carbos – made by dehydration synthesis of two simple sugars
  • 8. Dehydration Synthesis Inorder for monomers to bond, a water is released in the bonding process In the bonding of monomers – water is added and it is called hydrolysis
  • 9. 3 Types of Carbohydrates Monosaccharides – simple sugars Disaccharides – double sugars Polysaccharides – many sugars
  • 10. Monosaccharides – simple sugars C6H12O6 Manufactured by green plants Burned in Cellular glucose Respiration 3 examples fructose galactose
  • 11. Glucose, Fructose, and Galatose Are ISOMERS - same formula C6H12O6 Different Molecular arrangment.
  • 12. Disaccharides Two simple sugars together. C6H12O6 + C6H12O6 = ? C12H22O11 Dehydration synthesis
  • 13. Double Sugars - disaccharides: 2 monosaccharides joined Sucrose = fructose + glucose (table sugar) Maltose = glucose + glucose (malt sugar) Lactose = glucose + galactose (milk sugar)
  • 14. POLYSACCHARIDES (C6H10O5)n Macromolecules - many simple sugars joined
  • 15. POLYSACCHARIDESMacromolecules - many simple sugars joined Cellulose - cell walls in plants (fiber, wood paper, fruits, vegetables) *Most abundant organic compound on earth Starch - stored energy in plants (potatoes, grains, legumes, corn) Glycogen - animal starch (liver & muscle tissue)
  • 16. CHITINA polymer of glucoseFound in exoskeletons of arthropods(ex. Crabs, shrimp, lobsters)
  • 17. Starch Grain in Storage Cells
