Key Points

  • The research focuses on enhancing the understanding of ozone-induced dissociation in phosphatidylcholines using strontium adduction.
  • Investigated ozonolysis in the gas phase of strontium-adducted phosphatidylcholines.
  • Characterized specific fragments to localize double bonds in acyl tails.
  • Applied multivalent metal adduction to improve structural information.
  • Enhanced structural coverage by localizing double bonds to specific acyl tails.
  • Established multivalent metal adduction as a dual strategy for accelerated ozonolysis.
  • Provided insights for comprehensive lipid isomer characterization.

Abstract

-specific fragments allows double-bond localization to specific acyl tails, further enhancing structural information. Together, these results establish multivalent metal adduction as a dual strategy to accelerate ozonolysis and broaden its structural coverage, providing a powerful new approach for comprehensive lipid isomer characterization.
