A few days ago, researchers at the Lausanne Institute in the UK successfully transformed the metabolic pathway of flaxseed and produced a 12% yield of EPA and DHA. And 14%, this composition is similar to fish oil. EPA and DHA are omega-3 long-chain polyunsaturated fatty acids, which are very beneficial to human health. They can regulate the metabolism and immune system and are closely related to the development of nerves and cardiovascular and cerebrovascular health.
Scientists have studied a plant rich in linolenic acid, which is an essential component of EPA and DHA. Researchers discovered the constitutive genes that produce these beneficial lipids in seaweed and other photosynthetic marine organisms, and transferred these genes to flax.
First, after the researchers transferred five genes, the EPA content of flax seeds accounted for 24% of the total lipids, and then transferred to the other 7 genes, the DHA and EPA contents were 8% and 11%, respectively. The resulting DHA and EPA levels in the transgenic products reached 14% and 12%, respectively.
It is understood that the average cumulative amount of these lipids in transgenic flax seeds is comparable to that in fish oil, but natural flax does not produce these lipids. (Li Muzi)
