Is it due to the fact that animal lipids are rich in short chain fatty acids compared to plant lipids?
Hi,
I think its related to the presence of unsaturated fats in plants.
In animals and humans, short chain fatty acids (C4 to C8 that are saturated) are usual in the gut as they are produced by bacteria. Fat depots are related to intake. As a general rule, linoleic and arachidonic acids are main compounds in cells and tissues. In foodstuffs are characteristics of milkfat as result of fermentation process by rumen microbiota.
Animal fats are mainly composed of saturated fatty acids (C16, palmitic) but unsaturated can also be present.
To my knowledge oxidation reactions primarily occur on unsaturated fatty acids not in saturated. However plant oils are also composed of antioxidants that delay the start of oxidation.
I think that plant lipids are very rich with a number of antioxidants that retard to some extent the oxidation of long fatty acids.
Dear, this may be as result of oxidation reactions primarily occur on unsaturated fatty acids not in saturated and retardation of oxidation by incraesed number of antioxidant in plants unlike in animals and in humans.
