Ether bonds in membrane
WebPolyarylene ether nitrile (PEN) is a novel high-performance engineering plastic with various applications, particularly in thermoresistance-required fields. In this study, a well-known stimuli-response polydiacetylene monomer, 10, 12-pentacosadiynoic acid (PCDA), was encapsulated within electrospun PEN nanofibers to fabricate a colorimetric membrane … WebFatty acids: bacteria and eukaryotes produce membrane lipids consisting of fatty acids linked by ester bonds to a molecule of glycerol. In contrast, the archaea have ether bonds connecting fatty acids to molecules of glycerol. Although a few bacteria also contain ether-linked lipids, no archaea have been discovered that contain ester-linked lipids.
