Does anyone know of any formulas for calculating the energy yield in ATP of various fatty acids? The even-numbered saturated fatty acids are pretty-straightforward, but it gets tricky with the polyunsaturated and odd-numbered ones...Ideally, I want a formula where I can input the Chain length and the number and position of double bonds and get an output of the number of ATP's produced. Then I could program it into my graphing calculator and destroy my biochemistry exam on Friday For example:

B-oxidation , odd-numbered chain length saturated fat:

[(Chain length - 1)/2] - 1 = x

2.5(4x+1) + 1.5(2x+1) + x = 14x+ 4 = # ATP produced

The formulae for unsaturated fats will be tougher to derive though.

Can someone confirm if this is correct?
