Discuss the steps of fatty acid oxidation of a 14 carbon saturated fatty acid, beginning in the adipocyte and progressing though the steps of beta oxidation, Krebs, and ETC. What is the ATP yield?
In the first step of fatty acid oxidation, the fatty acid (R-COOH) is converted to its coenzyme A derivative in the following reaction: R-COOH + ATP + COA-SH -->R-CO-S-COA+AMP+PP The standard free-energy change (Delta G") for this reaction is -15 kJ/mol. Another reaction drives the reaction forward to a greater extent. This reaction is: A. Pyrophosphate is hydrolyzed to 2 phosphate molecules B. AMP is hydrolyzed to adenine C. The fatty CoA precipitates to remove it from the product side...
Determine the ATP equivalents that would be required to construct a fatty acid that is 18 carbons long, start with pyruvate. Assume that oxaloacetate is present and that fatty acid synthase is able to make a fatty acid of this length. Calculations MUST be clearly shown. Ignore the cost or gain associated with recycling oxaloacetate.
Biochemistry II: Calculating ATP from beta-oxidation In calculating the number of ATP molecules generated by the beta-oxidation of a single fatty acid molecule with an even number of carbons, a) Identify how the P/O ratios can be used (what are their significance), and b) help me to construct a formula given the P/O value of 3 for NADH and 2 for FADH2.
