Quantitative determination of alk-1-enyl- and alkyl-glyceryl ethers in neutral lipids and phospholipids.

abstract：:In offspring exposed in utero to a maternal diet high in fat (HF), we have previously demonstrated that despite similar birth weights, HF adult offspring at 6 months of age had significantly higher body weights, greater adiposity, and increased triacylglycerol (TAG) levels as compared to controls. We hypothesized that...
