Fig.2 shows the kinetics of COPs identifief during sun drying of shrimp. The formed in greater amounts were 7 HC and 7 HC, followed have been addressed by several reseachers under different conditions () Cholesterol oxidation can be initiated by hydrogen abstraction at C-7, followed by addition of an oxygen molecule, which leads to formed by high temperatures, direct exposure to UV light or by photo-oxdation through a type I reaction () Moreover, singlet oxygen formed by triplet sensitizer-ground state oxygen interaction (type II reaction) can react witn cholesterol via a non-radical mechanism, producing mainlyn5-OOH. The 5-OOH tends to convert rapidly, into 7-OOH, which later isomerizes to 7-OOH could produce 7-OH and 7-OH by reduction or 7-KC by dehydration. Later,7-HC and 7-HC could produce 7-KC by dehydrogenation () During sun drying of shrimp, a greater formation of 7-HCs () was observed as compared to 7-KC
