This mass spectral data is shown in Figure S7 of the publication.; Figure S7 shows that O attached precursor ions, [M+H+O*]+, are predominantly in the epoxide form. The [M+H+O*]+ ion is the product that [M+H]+ reacts with H2O microwave discharge (MSJ00187). The products of microwave discharge are mixture of gas-phase H*, OH*, and 3O (triplet O) radicals.; The instrument consists of QIT-TOF where Q selects [M+H]+ ion, IT is an ion trap chamber for the reaction of HAD, and TOF analyzes the product ions.; MS data of the substance is MSJ00178; Figure 1(A) Inset in the publication.; The sample was injected by direct infusion of methanol solution.; This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 19HP8024 to the Mass Spectrometry Society of Japan.; The lipid standard was purchased from Avanti Polar Lipids (Alabaster, AL).
