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

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
