WebJan 20, 2024 · pH-sensitive lipids represent a class of lipids that can be protonated and destabilized in acidic environments, as they become positively charged in response to low-pH conditions. They can be incorporated into lipidic nanoparticles such as liposomes, which are able to change their properties and allow specific drug delivery at the acidic … WebOct 1, 2024 · For lipid vesicles in a pH gradient, two types of particle/solute chemical interactions or reactions are possible: (i) titration of acidic or alkali headgroup functions (i.e. binding or dissociation of H + or OH − ); (ii) chemical reactions involving or catalyzed by H …

WebApr 9, 2024 · Many Archaea produce membrane-spanning lipids that enable life in extreme environments. These isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) may contain up to eight cyclopentyl and one cyclohexyl ring, where higher degrees of cyclization are associated with more acidic, hotter or energy-limited conditions. WebThese results indicate that the induction of genes implicated in the early and final steps of lipid biosynthesis contributes to their accumulation in the stationary phase. Our research suggests that a pH of 7.8 might be ideal to maximize growth and lipid accumulation. incident in banstead today
