49cockroaches are covered with a chitinous exoskeleton...
humans are covered by epithelial cells which have an outer covering of 2 layers of lipid and proteins...
might be it is this chitin which protects cockroaches bt the lipid and protein system gets disrupted in the dehydrating+oxidising + acidic conc.H2SO4
