Document Summary
Unit 1: lipids phospholipids, membrane structure, and membrane self-assembly. Whether or not a reaction is energetically favorable to proceed (ie: spontaneous: field of chemistry that deals with the likelihood of reactions occurring in a system. Energetically favorable = spontaneous: likely to happen, reaction moved from less table to more stable. Energetically unfavorable = not spontaneous: required energy input, reaction moves from more stable to less stable. Note: favourability/spontaneity does not tell you about reaction speed/rate. Mathematically, the total difference in stability ( g) between two states of a chemical system is given by: If h is then energy is released/available after the reaction. If h is + then energy was required for the reaction components of a system. If s is then the system is less free to move around. If s is + then the system is more free to move around. Strongly bonded (strong bonds, and/or many bonds) - Weakly bonded (weak bonds, and/or few bonds) + h.
