Mass spectra of the arrowed peaks in Fig. 3. Picolinyl esters were
prepared from FAMEs extracted from yeast transformed with pYESZFB10
grown in the presence of 18:2n-6 (A),
18:3n-3 (B), 20:3n-6
(C), and 20:4n-3 (D) and
analyzed by GC-MS as described in Materials and Methods.
The identities of the peaks were confirmed as 18:3n-6
(A), 18:5n-3 (B),
20:4n-6 (C), 20:5n-3
(D).
