In the experiment analyzing fatty acids in oils and fats using gas chromatography, extraction of fatty acid content was done from commercial oils and fats. Suggest a reason for the purpose of NaCl at step 3 Steps for extraction method: 1) Take enough material so that you have 0.1g of fat and add to boiling tube 2) Add 5ml CHCl3/MeOH and use foil to cover up and then vortex 3) Add 2ml NaCl solution and re-vortex 4) Transfer 500ul of...

Acholeplasma laidlawii is a bacterium that is unable to synthesize its own fatty acids and must therefore construct its plasma membrane from whatever fatty acids are available in the environment. Thus the A. laidlawii takes on the physical...

Fatty acids are carboxylic acids with a long, unbranched hydrocarbon chain
Fatty acids are carboxylic acids with a long, unbranched hydrocarbon chain. There are three main classes of fatty acids. Classify the fatty acids as saturated, monounsaturated, or polyunsaturated. Saturated Monounsaturated Polyunsaturated linoleic acid arachidonic acid oleic acid stearic acid palmitic acid
Omega-6 fatty acids are: O A form of saturated fatty acids O Contain a double bond...
Omega-6 fatty acids are: O A form of saturated fatty acids O Contain a double bond at the third omega carbon O Synthesized in the liver Help to regulate the constriction of blood vessels Omega-6 and omega-3 fatty acids are both polyunsaturated fatty acids that are essential to the human body. However, along with the chemical structures previously discussed, there are additional differences between the two essential fatty acids (EFAs). In the table, choose whether each statement concerns omega-3 or...

Q) Degradation and synthesis of fatty acids occur with different mechanisms. (A) What is a localization inside cells where degradation of fatty acids occurs? (B) What is an electron carrier (redox couple) used during fatty acid synthesis? (C) Give the name of enzyme that catalyzes condensation, reduction, dehydration, and reduction to synthesize fatty acids?
