Unformatted text preview: E.g carboxyl and phosphate groups Summary- Hydrogens o Nonpolar and hydrophobic- Properties depend on functional groups o Hydroxyl and carbonyl groups (polar) o Carboxyl and phosphate groups (polar, acidic) o Amino groups (basic) Polymers and macromolecules- Polymers o Long chain and linked monomers o Linked through condensation reactions- Macromolecules o Large polymers o Polysaccharids, proteins, DNA o Broken down by hydrolysis reactions Condensation and Hydeolysis- In condensation reactions: as monomers are added, water molecules is released therefore also called dehydration synthesis- In hydrolysis reactions: water molecules is consumes- hydrogen from water molecule attaches to one monomer, OH- from water molecule attaches to adjacent monomer Carbohydrates- Approx ratio o 1 carbon: 2 hydrogen: 1 oxygen o Exist naturally in ring formation- Monosaccharides o Simple sugar (3-7 Cs) Polysaccharids- Repeating units of simple sygars...
