WebProtein Folding -may be spontaneous or assisted -unfolded proteins often have "sticky" hydrophobic components at their surfaces, which can lead to formation of inactive aggregates -all cells have pathways for recycling/ degrading proteins that have been irreversibly misfolded Loss of Protein Structure results in Loss of Function WebFolded and unfolded proteins are often easily distinguished by virtue of their water solubilities, as many proteins become insoluble on denaturation. Proteins in the native state will have defined secondary structure, which can be detected spectroscopically, by circular dichroism and by nuclear magnetic resonance (NMR).
