This is the article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5611670/ I'm not a Chemist, so I can't understand the article very well.
The conclusion states that the molecules tested should not be called "piezolytes". Is this a nomenclature issue only? My only question is: does the presence of such molecules in deep sea organisms help in keeping proteins in their naturally folded state, resistant to denaturation due to high pressure or not?
