Document Summary
Fatty acid oxidation: have an understanding of the nomenclature and structure of common fatty acids. Fatty acids = alkyl chain with terminal carboxyl group. Unsaturated- up to 6 double bonds per chain (almost always in the cis configuration) Most of the fatty acids have a max of 6 double bonds- all mostly in the cis configuration. Can produce trans fatty acids- they can manufacture chemically. Must avoid these fats- making them trans (opposite. Most common fa in biological systems have even number of carbon atoms c16, c18, c20. We are only going to consider oxidation of an even number c, saturated, long chain fa. 16:1 (9) = 16 carbons, one double bond in the ninth position. Even number of carbons saturated and long chain. Icosatetraeno-d: know the basic structure of tag and how they are cleaved to give fa & glycerol. Must be hydrolysed by lipases to release energy. Breaks down the bonds between the glycerol and fatty acids.
