Azotosome
An azotosome (classical compound of "azote", French for nitrogen, and "soma", Greek for body〔(Life 'not as we know it' possible on Saturn's moon Titan )〕〔(Extra-terrestrial life based on methane possible on Titan show cell models )〕) is a theoretical membrane that could possibly serve as the basis for a cell membrane of a hypothetical methane–ethane-based living cell, analogous to the phospholipid bilayers found in all water-based life on Earth. Unlike a phospholipid-based cell membrane, an azotosome is composed of chemicals found in the methane–ethane liquid seas and in the atmosphere of Saturn's moon Titan, and it is capable of functioning in these conditions as a membrane. ==Conceptualization== The azotosome was proposed in February 2015 by researchers at Cornell University based on computer modeling of theoretical membrane structures. The researchers claimed to be inspired in part by science fiction writer Isaac Asimov's 1962 essay about the concept of non-water based life, entitled "Not as we know it".〔
