Polar Molecules Form Acids and Bases in water •H+ dissociates then associates with H₂O making H3O+ (Hydronium lan) Acids Substances that release protons When they dissolve in H₂O Forming HO -Higher the [H+] Concentration, the more acidic Bases Molecules that accept protons when dissolved in H₂O -Basic (alkaline PH-Show of Concentration of [H+] Many importare Cellular acids are weak (COOH Carboxyl group) Buffers Mixtures of weak acids + bases that will adjust pH Conc around pH by accepting or releasing Ht Small Molecules in Cells Cells are formed from Carbon Compounds •C readily forms 4 Covalent bond s Can link to other c atoms Organic Compounds Carbon Containing Compounds -All others are inorganic -often contain functional groups Methyl -CH3 Hydroxy - Carboxy -COOH Carbony! 2- -PO3 Phosphory! - NH3 Amino Four Major Families of Small Organic Molecules S SUGARS -monosaccharide.
