Figure 1 Molecular composition of cardiac phosphatidylcholine (PC) and phosphatidylethanolamine (PE) from controls and Barth syndrome (BTHS) patients with tafazzin (TAZ) mutation. Data are means of four measurements (two left ventricle samples and two right ventricle samples). Asterisks indicate a statistically significant difference between control and BTHS (p < 0.05). Diacylglycerol species are listed in the sequence in which they elute from the chromatography column. 16:0 = palmitic acid; 18:0 = stearic acid; 18:1 = oleic acid; 18:2 = linoleic acid; 20:4 = arachidonic acid; 22:5 = docosapentaenoic acid; 22:6 = docosahexaenoic acid.
