Metabolite Identification
Common NamePalmitelaidic acid
DescriptionPalmitelaidic acid is a trans fatty acid (the trans isomer of palmitoleic acid). Trans fatty acids are known to cause changes in plasma lipids and lipoprotein phenotypes, but the mechanisms involved are unknown. The major dietary sources of trans fatty acids are partly hydrogenated vegetable oils, mainly elaidic acid (t-18:1D9). Additional sources are animal and dairy fats [palmitelaidic acid (t-16:1D9) and t-vaccenic acid (t-18:1D11)] and partly hydrogenated fish oils. (very-long-chain trans fatty acids, ie, >C22) (PMID: 9734731 ). Palmitelaidic acid has been reported as the predominant trans-16:1 isomer in cheeses made with goat and ewe milks (PMID: 11026624 ).
