Qhov sib txawv tseem ceeb ntawm DHA thiab omega 3 yog DHA (docosahexaenoic acid) yog ib qho ntawm peb hom tseem ceeb ntawm omega 3 fatty acids pom nyob rau hauv cov dej hiav txwv, suav nrog cov ntses rog, shellfish, thiab marine algae thaum omega 3. fatty acid yog ib qho tseem ceeb polyunsaturated fatty acid uas muaj ob daim ntawv cog lus nyob rau hauv lub thib peb carbon txoj hauj lwm los ntawm methyl terminal.
A fatty acid yog carboxylic acid nrog cov saw ntev aliphatic. Ib qho aliphatic saw yuav muaj ob daim ntawv cog lus thiab. Saturated fatty acids tsis muaj ob daim ntawv cog lus ntawm carbon atoms ntawm hydrocarbon saw, thaum unsaturated fatty acids muaj ob daim ntawv cog lus ntawm carbon atoms. Fatty acids yog ib qho ntawm ob lub tsev thaiv ntawm lipid molecule. Lawv yog cov khoom tseem ceeb ntawm cov cell membranes. Tsis tas li ntawd, qee cov fatty acids, tshwj xeeb tshaj yog omega 3 fatty acids, yog qhov zoo rau peb kev noj qab haus huv.
