The New Information about Palmitoleic Acid-d14

Palmitoleic Acid-d14 is an ω-7 monounsaturated fatty acid that is a common constituent of the triglycerides of human adipose tissue. It is biosynthesized from palmitic acid by the action of the enzyme delta-9 desaturase.  It will last longer than the polyunsaturated fatty acids like linoleic or gamma-linoleic fatty acids. It is also known as an Omega-7 fatty acid.

Palmitoleic acid is a monounsaturated fatty acid with one double bond (C16:1).  The double bond means that it will go rancid more quickly than some of the saturated fatty acids such as Palmitic or Stearic acid.  It is found mainly in animal fats, particularly in fish and marine mammals, and is also present in the seeds of plants of the Proteaceae family. Palmitoleic acid, or (Z)-9-hexadecenoic acid, is an omega-7 monounsaturated fatty acid with the formula CH3(CH2)5CH=CH(CH2)7COOH that is a common grammatical constituent of the glycerides of somebody adipose tissue. Dietary sources of palmitoleic acid include a variety of animal oils, vegetable oils, and marine oils.

In contrast to a diet enriched with oleic acid, palmitoleic acid-based diets raise low-density lipoprotein (LDL) cholesterol and lower high-density lipoprotein (HDL) cholesterol much like that of a saturated fatty acid, even when dietary intake of cholesterol is maintained at a low level. It is confront in all tissues, but broadly speaking bumped inward more high-pitched compactnesses fashionable the liver. Other preliminary research indicated that palmitoleic acid could have a role as a signaling molecule affecting body weight. This work is consistent with previous observations that palmitoleic acid, among other fatty acids available in the diet, may be used by enzymes affecting fat oxidation.
