Alkenone fame fattyacids
Fatty acid methyl esters (FAME) are a type of fatty acid ester that are derived by transesterification of fats with methanol. The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel. FAME are typically produced by an alkali-catalyzed reaction between fats and methanol in the presence of base such a… WebOther studies have focus on two vital fatty acids, Eicosapentaenoic acid (EPA) [38-40] and docosahexaenoic acid (DHA) [41-44], which can affect blood pressure, lipoprotein metabolism and platelet and endothelial function. It is possible that alkenones derived from Isochrysis could potentially produce similar effects. Conclusiont
