In established areas many spiders may populate the home. The biological effects of either molecule in human membranes or insects aren't completely known, he said, but they are likely to be very different. This tiny protein has a very powerful effect though. The specific antivenom needed depends on the species involved. The protein acts to cleave off the head portion of the lipids, leaving behind, scientists long have assumed, a simple, linear, headless lipid molecule.
