Document Summary

Sept. 10 5:30-7:30 natural history museum: polymers. Polymers are made by the same chemical mechanism ie. dehydration reaction. Dehydration reaction: hydroxyl group and h are replaced bt a covalent bond, producing a polymer releasing h2o. H2o molecule replaces a covalent bond, adds hydroxyl to one and h to the other. Macromolecules are broke down through: carbohydrates. Sugar>monosaccharides: monomer o. are based on (aka simple sugars) 3,5, 0r 6 carbons sugar families named according to # of c. Arrangement of h and oh at a single asymmetric carbon caused different properties. Pemtoses and hexoses spontaneously cirilarize to rings ( linear form is rare) When they form c#1 is an asymmetric carbon so two different enantiomers are possible. Monosaccharide components and bond position determine disaccharide identity. Properties determined by monosaccharides monomers and made from a/b monomers. Different properties are made from a/b monomers. Cl can form covalent bonds (splenda) or ionic bonds (nacl) Starch, glycogen (carb storage in plants and animals)
