Concentration of lysophophatidylcholine (LPC) and phosphatidylcholine (PC) with a particular fatty acyl chain in plasma of dairy cows during lactation.

1All metabolites, except for LPC 18∶1 were Log10 transformed to obtain equal variance. Means and SEM represents non-transformed data.2Two or three possible combinations of fatty acids were identified by the same product ions from HILIC LC-MS/MS.3Phosphatidylethanolamine N-methyltransferase (PEMT) ratio = (16∶0/22∶6,18∶1/20∶5,18∶2/20∶4+18∶1/22∶6+18∶0/22∶6,18∶1/22∶5)/(16∶0/16∶1+16∶0/20∶5, 16∶1/20∶4+16∶0/16∶0+16∶0/18∶2+16∶0/18∶1+16∶0/20∶4+18∶0/20∶4+18∶0/20∶3+18∶0/22∶5+18∶0/18∶2, 18∶1/18∶1+18∶0/18∶1+18∶1/20∶4,18∶0/20∶5,16∶0/22∶5).abcdefMeans within a row with different superscripts differ (PConcentration of lysophophatidylcholine (LPC) and phosphatidylcholine (PC) with a particular fatty acyl chain in plasma of dairy cows during lactation.
