Research progress in polyunsaturated fatty acids

Polyunsaturated fatty acids(PUFAs)is a unique bioactive substances,it has important physiological function to human body.ω-3 and ω-6 polyunsaturated fatty acids are precursor of eicosanoids synthesis.Their homeostasis plays an important role in stable membrane function,regulation of gene expression,maintaining cell factors and lipoprotein balance,fighting cardiovascular diseases,and promotion of growth.And now it is one of the hotspots of nutrition biochemical.As the expansion of PUFAs application fields,more and more pure PUFAs lipids are needed.In recent years,people have been exploring new sources of PUFAs,namely using microorganism techniques to produce PUFAs.The research progress of PUFAs physiological functions and sources,and emphatically expounds ω-3 and ω-6 polyunsaturated fatty acid metabolism,physiological functions,the scale of ω-3 and ω-6 polyunsaturated fatty acids,fermentation,etc were introduced.
