Salinity vs Lipid hydroperoxide stability
« on: April 13, 2018, 01:26:55 AM »
Does high salinity(about 3 %) affect stability of lipid hydroperoxides?

I had reasons to conduct experiment on lipid hydroperoxide determination in a seawater-like salinity. I noticed my hydroperoxide standard quickly decomposed even before I could introduce the detecting probe. This was not so in MQ.

Please does high salt content affect hydroperoxide stability?

What is the chemistry behind it and kindly recommend some materials that explains it in a simple way?

Thank you

Curious. Could there be transition metal contaminants?

@ Wildfyr: Thank you for your question.

Transition metal contamination is very possible. If that is the case, one can expect the effect to be more pronounced in Riverwater than in seawater since the former will likely have a higher concentration of TM than the latter. However, the hydroperoxide standard were much more stable in river water than in seawater.
Hence, TM may not be the main issue here.
