Essential fatty acids are except:
The essential fatty acids are polyunsaturated fatty acids, linoleic acid (18:26) and linolenic acid (18:33). Arachidonic acid (20:46) is derived from dietary linoleic acid and is present primarily in membrane phospholipids. Impoant derivatives of linolenic acid are eicosapentaenoic acid (20:63) and docosahexaenoic acid (DHA, 22:63) found in human milk and brain lipids.Palmitic acid is a common saturated fatty acid.
