A.CH3(CH2)14COO

B.CH3(CH2)5CH=CH(CH2)7COO

How Many ATP will be formed after beta- oxidation of A and B?

i dont think you need them. i just want what to know the ATP difference between saturated and unsaturated compound

16 c(palmitoleic (unsaturated) , 16c palmitic acid (saturated)

Answer #1

Complete oxidation of one molecule of palmitic acid yields 129 ATP molecules

C15H31COOH+8CoASH+ATP+7FAD+7NAD++7H2O → 8CH3COSCoA+AMP+PPi+7FADH2+7NADH+7H+

Each molecule of acetyl-CoA yields 12 ATP (12 × 8 = 96); FADH2 yields 2 ATP (7 × 2 = 14); NADH yields 3ATP (7 × 3 = 21); and two high-energy bonds are consumed (-2; ATP → AMP + PPi). Thus, net ATP production is 129.

Beta-oxidation of unsaturated fatty acids changes the ATP yield due to the requirement of two possible additional enzymes. Beta oxidation of unsaturated fatty acid skips one FAD → FADH2 step hence has lower ATP production than saturated fatty acid.

    Stearic acid (CH3(CH2)16COOH) is a common long-chain acid found in waste streams. Many microorganisms are capable of using stearic acid and derived metabolites as substrates. Determine the maximum ATP yield (mmol ATP/g stearic acid) that can be achieved from the complete oxidation of stearic acid to water and CO2 during aerobic microbial respiration in typical cellular environments. For your calculation, you may assume that after electron transport driven ATP synthesis, 3 ATP molecules are produced per NAD(P)H and 2 ATP...
