Document Summary
Amino, hydroxyl, carboxylic acid, sulfhydryl are all capable of bonding w h/bonds. Attracted to water, interact and have an affinity for water. Hydrophobic effect: association of nonpolar groups with each other in aqueous systems: driven by the tendency of surrounding water molecules to seek their most stable state. Covalent, ionic: partial charges negative charge on oxygen in h20, positive charge on hydrogen in h20. Hydrophobic tail, not soluble in water -- due to lipid bilayer. Glycerol one of the three dehydration reactions in the synthesis of a fat. Do not have covalent bonds that link monomers to polymers: fats glycerol + fatty acid. Used for storage: phospholipids glycerol + 2 fatty acids + phosphate. Polar hydrophilic head and nonpolar hydrophobic tails. Make up membranes lipid bilayer stable b/c of hydrophobic effect. Amount of kinked tails affects fluidity: steroids 4 ring carbon chains. Dehydration reaction synthesis through removal of water. Hydrolysis breaking down polymers, h20 as product.
