These omega-3 fatty acids are found in the eyes and brain and are essential for normal growth, visual acuity and cognitive development. They may also play an important role in the prevention and treatment of heart disease.
Linolenic acid can be used in the synthesis of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. EPA and DHA acids are primarily found in fish oils, and marine algae.
Linolenic acid serve as precursors of hormone-like compounds called eicosanoids. Linolenic acid also is an important component of biological membranes, particularly in nerve tissue and the retina.
