Abstract

The 14C-labeled short-chain fatty acid 10-methylhexadecanoic acid (10-Me-160) as well as its hitherto undescribed 10R and 10s antipodes was incorporated into the marine sponge Aplysina fistularis and transformed in situ into 22-methyl-5, 9-octacosadienoic acid (22-Me- A5s9-28: 2) by chain elongation. No qualitative specificity between the two enantiomers was observed.[3H] Methionine was also incorporated into the sponge to investigate the ...
