LS 2 Midterm 1 Study Guide Lecture 1: Biological Molecules Chemical Bonds -Covalent - strong, sharing e - -Non-covalent - weak ? Ionic - i.e. NaCl; polar/non-polar (very strong) ? Hydrogen - H interaction with NOF ? Hydrophobic interactions - fatty acids, nonpolar groups ? Van der Waals forces - slight positive/negative charges interacting Water -High specific heat homeostasis -Adhesive properties (good lubricant) ? High surface tension ? Cohesion -Good solvent - nutrients, chem rxns, oxygen and carbon dioxide -Solid form is less dense than liquid (more stable H-H bonding) -High heat of vaporization - sweating helps cooling -pH = 7 Math -1 mole = 6.02x10 molecules 22 -pH = -log[H ] + ? Low pH = acidic - release H ; generally organic acids are weak and inorganic are strong + ? High pH = basic - release OH or take up H - + Lipids -Prostaglandins - derivatives of fatty acids which act similar to hormones -Double/triple bond do...
