The substrate D5-18:3n-3 decreased over the 96 h whereas
all other DFA increased. However, the great majority of
tracer was recovered as D5-18:3n-3 (Table I). The
elongation product D5-20:3n-3 was the next most abundant
DFA increasing from 2.7% of DFA at 24 h to
5.4% by 96 h. The desaturation products D5-18:4n-3,
D5-20:5n-3 and D5-22:6n-3 were present in very low
amounts (Table I).
