The number of molecules of acetyl-CoA that are produced by the catabolism of palmitic acid and the number of β oxidations that are needed for this process to occur has to be determined. Concept introduction: Fatty acids are aliphatic mono- carboxylic acids that are mostly obtained from the hydrolysis of natural fats and oils. They have a general formula R − ( C H 2 ) n − C O O H , n is mostly an even number of carbon atoms (4 to 20) with a few exceptions that have an odd number Fatty acids in the body are mostly oxidized by β oxidation. β-oxidation is the oxidation and splitting of two carbon units at β - carbon atom. This results in sequential removal of 2 carbon fragments as acetyl CoA until the complete oxidation of fatty acids.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
