| Material Notes | A major component of lipids of marine plants and animals, also found in plant oils, e.g. Macadamia ternifolia (small-fruited Macadamia nut) seed oil (20%) Palmitoleic acid, or (Z)-9-hexadecenoic acid, is an omega-7 monounsaturated fatty acid that is a common constituent of the glycerides of human adipose tissue. It is present in all tissues, but generally found in higher concentrations in the liver. It is biosynthesized from palmitic acid by the action of the enzyme delta-9 desaturase.; fatty acids, Monounsaturated; Palmitoleic acid, or 9-hexadecenoic acid, is an unsaturated fatty acid that is a common constituent of the glycerides of human adipose tissue. Present in all tissues, generally found in higher concentrations in the liver. Macadamia oil (Macadamia integrifolia) and Sea Buckthorn oil (Hippophae rhamnoides) are botanical sources of palmitoleic acid, containing 22 and 40% respectively. -- Wikipedia Palmitelaidic 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). [HMDB] |
