上游充通大兽 Archaeal(古菌的)Membranes Are Built from SHANGHAI JIAO TONG UNIVERSITY Ether Lipids with Branched Chains Archaeal Membranes Are Built from Ether Lipids with Branched Chains 古菌的质膜由醚键连接（而非酯键），具有分叉的饱和烷烃链 NH3* H3C H3 H3 Membrane lipid from the archaeon Methanococcus jannaschii 分叉、饱和的烷烃链对于古菌适应生存环境具有重要意义。 These branched,salurated hydrocarbons are more resistant to oxidation,which may help these organisms to with stand the extreme conditions,such as high temperature,low pH,or high salt concentration.Archaeal (古菌的) Membranes Are Built from Ether Lipids with Branched Chains Archaeal Membranes Are Built from Ether Lipids with Branched Chains 古菌的质膜由醚键连接（而非酯键），具有分叉的饱和烷烃链 These branched, salurated hydrocarbons are more resistant to oxidation, which may help these organisms to with stand the extreme conditions, such as high temperature, low pH, or high salt concentration. 分叉、饱和的烷烃链对于古菌适应生存环境具有重要意义
