(Top) Structural formula of 3SP-CoA; (bottom) mass spectrometric data. The first is an ESI spectrum of 3SP-CoA in positive mode. In the middle is an MS spectrum of the parent ion (m/z = 888 Da). Two main fragments (m/z = 428 Da and m/z = 381 Da) were obtained. At the bottom, further fragmentation of the parent m/z 381 Da yielded daughter ions (m/z = 315 Da and m/z = 261 Da).
