Document Summary
Barrier between living organisms and the outside (cell membrane-amphipathic) Naming: general nomenclature: numbering from carboxyl carbon. Number of carbons in fatty acid chain 18: 1 double bond at position 9. Polysaturated has more than one: omega nomenclature: the carbon furthest from the carboxylic acid is called omega. # 3 refers to double bond from fatty acid: butter: solid at rm temp (saturated, margarine: liquefy (higher % of unsaturated fatty acids) Has no double bonds in the hydrocarbon chain. Transported into different lipoprotein particles can lead to clogging arteries. Extract less energy by cleaving carbon double bonds they require more energy to cleave) Liquid at room temp (when they segregate away from water in an aqueous environment, their chain plays a role in how compact they become inside the cell have a kink (steric hindrance for compaction) Double bonds: trans (bad) or cis most of them are in cis configuration.
