Table 2: Methods of calculation of SFA, UFA, desaturation and lipid peroxidation indexes.
Index | Molecules |
---|---|
Saturated Fatty Acids (SFA) | C12:0+C14:0+C16:0+C18:0+C24:0 |
Monounsaturated Fatty Acids (MUFAs) | C16:1+C18:1C+C18:1T+C24:1 |
Polyunsaturated Fatty Acids n-6 (n-6 PUFAs) | C18:2:6+C18:3:6+C20:3:6+C20:4:6 |
Polyunsaturated Fatty Acids n-3 (n-3 PUFAs) | C18:3:3+C20:5:3+C22:5:3+C22:6:3 |
Total Polyunsaturated Fatty Acids (PUFAs) | n-6 PUFAs + n-3 PUFAs |
n-6/n-3 Index | n-6 PUFAs/n-3 PUFAs |
Desaturation index Delta 9 | C18:1 and C18:0 ratio |
n-3 Delta 5 index | C22:6:3 and C22:5:3 ratio (n-3 family) |
n-6 Delta 5 index | C20:4:6 and C20:3:6 ratio (n-6 family) |
n-3 Lipid peroxidation index | C22:6:3/C12:0 |
n-6 Lipid peroxidation index | C20:4:6/C12:0 |
