Because in the first reaction of beta oxidation of unsaturated fatty acids a trans double bound is formed from cis-double bound by an izomerase without formation of FADH2. Thus the first oxidation step is skiped and hence less energy yield.

Lipid that are positive to acrolein test?

Lipids that are positive to the acrolein test include unsaturated fatty acids and lipids that have undergone lipid peroxidation. Acrolein reacts with the double bonds present in unsaturated fatty acids, producing a dark color in the presence of specific reagents. This test is used to assess the degree of lipid oxidation in food products.


What are producing more ATP in between saturated and unsaturated fatty acids?

In saturated fatty acid oxidation, the first step is a dehydrogenase reaction. This yields a trans double bond on carbons 2 and 3 from the CoA end. A product of the reaction is FADH2 which can be used to make ATP. In oxidation of an unsaturated fatty acid, the double bond is not recognized by the dehydrogenase reaction therefore you have to use a secondary isomeration reaction to produce the same product as you did in saturated fatty acid oxidation. This skips the effective "first step" and does not produce FADH2 meaning less ATP is produce.


What are unsaturated fatty acids?

Unsaturated fatty acids are fatty acids that have double bonds in their long carbon chains.


On a basic level how does fatty acid oxidation work?

Fatty acid oxidation is the process in which fatty acids are broken down by tissues to produce energy. Fatty acids are the residue left from fats being broken down.


Are fatty acids saturated or unsaturated?

Fatty acids can be either saturated or unsaturated. Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.
