Document Summary

Ex. glucose + fructose sucrose glucose + glucose maltose glucose + galactose lactose: polysaccharides, 100s 1000s of joined saccharide units, examples, starch, glucose molecules, surplus glucose storage in plants, glycogen, glucose monomers (highly branched, animal glucose storage, cellulose, glucose monomers (different isomer/anomeric form than starch, major component of cell walls, chitin, n acetylglucosamine monomers, component of arthropod exoskeletons, bonds formed between monosaccharides are the result of a dehydration reaction (or condensation reaction, *all molecules discussed are joined by a dehydration reactions > monomer to monomer, addition of a monomer to a polymer. Hydrophilic: having an affinity to water dissolves in water: examples of important biological lipids, fatty acids, long hydrocarbon chain with an acid carbonyl group ( cooh) at one end, fatty acids vary wrt number of ch2 groups and the # of double bonds, unsaturated bonds are double of triple bonds (i. e. do not have max number of hydrogens or other substituents palmitic acid.
