Identification of (S)-11-cycloheptyl-4-methylundecanoic acid in acylphosphatidylglycerol from Alicyclobacillus acidoterrestris

Add time:09/07/2019    Source:sciencedirect.com

A method is described for the identification of molecular species of acylphosphatidylglycerols containing a branched cyclo fatty acid ((S)-11-cycloheptyl-4-methylundecanoic acid; brc19:0) from Alicyclobacillus acidoterrestris and its identification as picolinyl ester by means of GC–MS. The combination of TLC, negative RP-HPLC–ESI–MS/MS, enzymatic hydrolysis, and GC–MS was used to identify unusual molecular species of acylphosphatidylglycerols with cyclic and branched FA. The acid, brc19:0, was also synthesized to unambiguously confirm its structure. According to feeding experiments with 13C-labeled propionate, the C3 internal unit (branched methyl) of brc19:0 is assembled from propionate and not from methionine.
