Nm. Carballeira et al., IDENTIFICATION OF NOVEL ISO ANTEISO NONACOSADIENOIC ACIDS FROM THE PHOSPHOLIPIDS OF THE SPONGES CHONDROSIA-REMIFORMIS AND MYRMEKIODERMA-STYX, Journal of natural products, 56(10), 1993, pp. 1850-1855
The previously unreported 27-methyl-5,9-octacosadienoic acid [1] and 2
6-methyl-5,9-octacosadienoic acid [2] were identified in the phospholi
pids of the Caribbean sponges Chondrosia remiformis and Myrmekioderma
styx. Both sponges also contain the novel 15-methyl-5,9-hexadecadienoi
c acid [3] in their phospholipids. These results extend the possible c
hain lengths in DELTA5,9 iso/anteiso fatty acids in sponge phospholipi
ds from C-17 to C29.
