Considering that organic selenium (as seleno-methionine) is not metabolically differentiated from sulfur-methionine, is it possible that this substitution occurs also on Fe-S proteins at the Complex I and II of of mitochondrial electron transport?
Hi Danynl
Yes, I think it can be possible! because Se replaces S in certain molecules. But probably this phenomenon could be more obvious when Se is present in high concentration in environment.
Hi Muhammad,
Thank you for your answer. Just to go a little further, so you think that if an animal is supplemented with Se, this replacement is possible?
Do you have any reference that you could forward to me?
Hi,
I think so. I have been working with plant treated with Se. and what I found when certain plant species are treated with high concentration of Se the total concentration of S (in acid digested samples) is affected negatively in above ground plant parts and plants protein contents are also affected by supplementation with high Se content in soil.
