PtdCho molecular species in the ECT-deficient liver. A, molecular species fingerprint of PtdCho from a typical control liver. B, PtdCho molecular species fingerprint from a typical ECT-deficient liver. Data are representative of duplicate analyses on three different male mice of each genotype. The identification of the primary phospholipid molecular species in each of the major peaks was based on the fatty acid composition and the preponderance of saturated fatty acids in the 1-position and unsaturated fatty acids in the 2-position of hepatic phospholipids.
