Application

Palmitoleic acid has been used:
  • to supplement Minimum Essential Media alpha (MEMα) to culture mouse spermatogonial stem cells (SSCs)
  • as a component of a defined serum-free medium for the long-term propagation of SSCs
  • in Dulbecco′s Modified Eagle Medium (DMEM) in the media for fatty acid treatment to assure a physiologic ratio between bound and unbound free fatty acid (FFA)

Biochem/physiol Actions

Palmitoleic acid is a 16-carbon, omega-7, monounsaturated fatty acid that is enriched in the triglycerides of human adipose tissue and in liver.

Saturated free fatty acids induce hepatocyte lipoapoptosis. This lipotoxicity involves an endoplasmic reticulum stress response, activation of JNK, and altered expression and function of Bcl-2 proteins. The mono-unsaturated free fatty acid palmitoleate is an adipose-derived lipokine which suppresses free fatty

Palmitoleic acid has been shown to regulate adipokine expression and systemic metabolic homeostasis in animal studies. However, its association with human metabolic diseases remains controversial. We aimed to investigate associations of erythrocyte palmitoleic acid with adipokines, inflammatory markers, and metabolic

Dairy consumption is linked to a lower risk of type 2 diabetes, but constituents responsible for this relation are not established. Emerging evidence suggests that trans-palmitoleate (trans 16:1n-7), a fatty acid in dairy and also partially hydrogenated oils, may be

De novo lipogenesis has been implicated in prostate carcinogenesis, and blood levels of specific saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) could reflect activity of this pathway. We used gas chromatography to measure blood SFA and MUFA levels

The expansion of lower-body adipose tissue (AT) is paradoxically associated with reduced cardiovascular disease and diabetes risk. We examined whether the beneficial metabolic properties of lower-body AT are related to the production and release of the insulin-sensitizing lipokine palmitoleate (16:1n-7).
