(A) Positive ion electrospray ionization of synthetic 1-hexadecanoyl-2-oleoyl-3-linoleoyl glycerol (16:0/18:1/18:2-TAG) followed by collision induced dissociation of the [M+NH4]+ at m/z 874.8. Abundant product ions correspond to neutral loss of each fatty acyl group as a free carboxylic acid and ammonia (NH3). (B) Positive ion electrospray ionization of synthetic [1,1,2,3,3]-D5-1-arachidonoyl-2-linoleoyl-3- arachidonoyl glycerol (D5-20:4/18:2/20:4-TAG) followed by collision induced dissociation of the [M+NH4]+ at m/z 949.8. Abundant product ions correspond to neutral loss of each fatty acyl group as a free carboxylic acid and ammonia (NH3).
