Italian physician Francesco Redi (1626–1697),

His hypothesis was supported when maggots developed in the uncovered jars, but no

maggots appeared in either the gauze-covered or the tightly sealed jars. He concluded that

maggots could only form when flies were allowed to lay eggs in the meat, and that the

maggots were the offspring of flies, not the product of spontaneous generation.

polylysine is a random coil at pH values below about 11, where repulsion of positive charges prevents helix formation. At pH 12, where polylysine is a neutral peptide chain, it readily forms an a-helix.
