Document Summary
Learning outcomes: describe structure of fatty acids, naming conventions, discuss the process of fatty acid synthesis and the fate of fatty acids, tag synthesis and storage, understand -oxidation (fatty acid degradation) and the net energy yield. Found either free or as fatty acyl esters (mostly in tags) Fas with no double bonds are saturated (max number of h atoms bound) Fas with 1 or more double bond are unsaturated (fewer h atoms bound) In nature (including in human cells) fas have an even number of carbons. C16 and c18 are the predominate fas (palmitic, palmitoleic, steric and oleic acids) Linoleic acid precursor to arachidonic acid which is the substrate for prostaglandin synthesis. Linolenic acid precursor to other -3 (omega 3) fas involved in growth and development. Arachidonic acid (common name): 20:4 (5,8,11,14) and -6 fas: number of carbons with 4 double bonds.
