Well, recall that acyl coenzyme adhdrogenase basically generates a double bond between carbon two and carbon three. And the problem with this molecule is we already have a double bond between carbon three and carbon four. And so this enzyme cannot generate a double bond between carbon two and carbon three because of the presence of another double bond between carbon three and carbon four. So this molecule is not a substrate for acyl coenzyme adhdrogenase. So how exactly the cells of our body actually prevent this problem, fix this problem? Well, one thing that our cells do is they take this molecule and transform it into an intermediate that can be fed into the beta oxidation pathway.
