Incorporation of 13C-18:2 into phosphatidylglycerol. Cardiomyocytes isolated from (A) nonHF and (B) HF SHHF rat hearts were incubated in 13C-18:2, 13C-18:2 + BEL, or 13C-18:2 + R-BEL for up to 72 h. Incorporation of 13C-18:2 into PG was measured by quantifying different species of PG with either 16:0, 18:1, 18:2, or 13C-18:2. Data are presented as mean ± SE (n = 4). * P < 0.05 versus control value within analyte; #
P < 0.05 versus 13C-18:2, 24 h value within analyte.
