Presentation Transcript

  1. Organic Molecules

  2. Amino acid Organic Molecules Amino acid Amino acid • Carbon = building block of organic molecules • Carbon is unique • Only 4 outer electrons • May bond with 4 other atoms to become stable • Monomer: Small carbon molecules • Ex: Amino acid • Polymer: chain of linked monomers • Ex: Protein Amino acid Amino acid Amino acid Amino acid Amino acid Amino acid Amino acid

  3. Carbon creates 4 bonds to be stable

  4. Carbohydrates • Readily available food source • C1: H2: O1 ratio • Ex: Glucose = C6 H12 O6 • Monomer: Monosaccharides • Simple sugars • Bond to form larger sugars • Polymer: Polysaccharide • Complex sugars Fructose (monosaccharide) Glucose (monosaccharide) Sucrose (Polysaccharide)

  5. Polymer: Polysaccharide • Long chain of monosaccharides • Ex: Starch (pictured) : excess plant sugar converted & stored • Ex: Glycogen: animal starch stored in liver & muscles • Ex: Cellulose: used in plants to make cell walls

  6. Kobe Kuiz How many electrons does Carbon have in the 1st energy level? 2nd energy level? Which type of organic molecule is most commonly used as energy for cells? If a carbohydrate has 8 carbon atoms, how many oxygen and hydrogen atoms will it most likely contain? What are the monomers of carbohydrates called? What are the polymers of carbohydrates called? Which polymer is stored by animals? Which polymer is stored by plants?
