"The triacylglycerols (TAG) containing dihydroxy fatty acids have been recently identified by mass spectrometry in castor oil. These new dihydroxy fatty acids were proposed as 11,12-dihydroxy-9-octadecenoic acid (diOH18:1), 11,12-dihydroxy-9,13-octadecadienoic acid (diOH18:2) and 11,12-dihydroxyoctadecanoic acid (diOH18:0)," scientists in the United States report.
"The ratios of regioisomers of the TAG were estimated by fragment ions from the loss of fatty acids at the sn-2 position as alpha,beta-unsaturated fatty acids by electro spray ionization-mass spectrometry of the lithium adducts (MS3). The content of regioisomeric diOH18:1-OH18:1-diOH18:1 (ABA, with two ...
