Lecture 6 1.) Structures 2.) Metabolism 3.) Digestion Essential fatty acids - Rats were had fat – free diet -> shorter lifespan, derivative, kidney damage, impaired fertility Nomenclature C#:# # of carbon # of double bonds w-# location of c doubld bond from omega end Or n-# 1.) Saturated F.A. (SFA) 2.) Nonunsaturated F.A. (MUFA) C=C 3.) Polyunsaturated F.A. (PUFA) double bonds 1.) E.g Stearic Acid C 18 : O (don’t need to remember) Palmitite Acid C16: O Be able to provide name or draw structure C#:#, W# 2.) E.g.Oleic Acid C18:1 W-9 3.) E.G. linoleic Acid C18:2 W-6 Omega 3: alpha linolenic acid C18:3 (w-3) Chain length of F.A. - Shorter the chain length or m ore unsaturated (more double bonds) Lower the m elting point - Animal fat m ore SFA -> solid @ room te m p - Vegetable oil m ore PUFA -> liquid @ room te mp
