1Fatty acids are designated by the number of carbon atoms followed by the number of double bonds. The position of the first double bond relative to the methyl (n) end of the molecule is also indicated.
2SFA: saturated fatty acids, MUFA: monounsaturated fatty acids, PUFA: polyunsaturated fatty acids; ∑SFA: the sum of C14:0, C16:0, and C18:0; ∑MUFA: the sum of C16:1 (n-7) and C18:1 (n-9); ∑(n-6) PUFA: the sum of C18:2 (n-6) and C20:4 (n-6); ∑(n-3) PUFA: the sum of C18:3 (n-3), C20:5 (n-3), C22:5 (n-3), and C22:6 (n-3); ∑PUFA: the sum of ∑(n-6) PUFA and ∑(n-3) PUFA.
