Biological Activity

[Description]:

6,9,12,15-octadecatetraenoic acid (Glycerol α-monoelaidate) is a rare omega-3 series polyunsaturated fatty acid. In normal people, it accounts for less than 0.25% of serum phospholipid fatty acids. It is found in certain natural oils, such as echium and blackcurrant, and to the extent that these oils are incorporated into nutraceuticals, stearidonic acid can be an important polyunsaturated species in the human diet. Ethyl stearidonic acid, an ester of the free acid, is less water soluble but more suitable for formulating stearidonic acid-containing diets and dietary supplements.
