Lab 12: Saponification – Making Soap Objective: To make soap using the process call saponification, an organic form of the neutralization reaction that an acid reacts with a base to form a salt. Introduction: A soap is the sodium or potassium salt of a long chained carbohydrate called a fatty acid. A fatty acid usually contains between 12 – 18 carbon atoms. Fatty acids are esters of either animal or vegetable fats. They are called triglycerides if they are solids at room...
SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids?...
SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids? A.Because the lipid bilayer may confuse the incoming fatty acids as part of the membrane. Without the carnitine shuttle, the lipid bilayer may incorporate the fatty acids into the membrane instead of breaking it down via oxidation. B.Because fatty acids cannot directly pass through the mitochondrial membranes. C.Because fatty acids must be "tenderized" - i.e., multiple functional groups are added in order to facilitate...

CH3–(CH2)18–COOH b. CH3–(CH2)7–CH=CH–(CH2)7–COOH c. CH3–(CH2)4–CH=CH–(CH2)2–(CH2)6–COOH d. CH3–CH2–(CH=CH–CH2)4–(CH2)2–COOH Which of the following types of compounds are expected products...
Why would it be advantageous to plants to be able to get acetyl-CoA from fatty acids?...
Why would it be advantageous to plants to be able to get acetyl-CoA from fatty acids? -Fatty acids are the macromolecule most easily taken up by the roots of the plant -Plants lack the ability to synthesize carbohydrates -Energy derived from photosynthesis primarily comes in the form of fatty acids -Seeds have a limited amount of space and fatty acids are the most energy dense macromolecule
