OxidationofPolyunsaturatedFattyAcid
Unsaturated fatty acids are those that contain one or more double bonds in their alkyl-chain. Polyunsaturated fats with two double bonds usually have one between carbons 9 and 10 in the alkyl chain and another three carbons away (carbons 12-13). The presence of a double bond in the fatty acid chain changes the shape of the side group, and alters membrane fluidity when present in phospholipids. Polyunsaturated fatty a......閱讀全文
