Document Summary
Substance that is insoluble in water but soluble in non-polar solvents. Name four roles lipids serve in biological systems. Describe their physical characteristics (i. e. , even # carbons, double bond location/geometry, solubility, amphipathic, etc). Understand how to name a saturated and unsaturated fatty acid, including double bond location. What is meant by omega-3 or omega-6 fatty acids, understand this nomenclature. Carbons are numbered from the alpha end (cooh) Naming: #carbon:#double-bond(deltacarbon #s where double bonds are located) An essential fatty acid is one that cannot be manufactured by the body: from the omega end, the body cannot put double bonds from the 1st to. Omega-3 has its first double bond from the omega end at carbon 3: omega-6 has its first double bond from the omega end at carbon 6. Fatty acids to know: myristic acid, palmitic acid, stearic acid, oleic acid, -linoleic acid, linolenic acid, arachidonic acid. Palmitic (16c), stearic (18c), myristic (14c), straight saturated hydrocarbon chains.
