Isoprenoid fatty acids in antarctic krill ( Euphausia superba)
Abstract In an attempt to elucidate the origin of phytanic (3,7,11,15‐tetramethylhexadecanoic), pristanic (2,6,10,14‐tetramethylpentadecanoic) and 4,8,12‐trimethyltridecanoic acids found in small quantities in whales, the fatty acid composition of the lipids from Antarctic krill ( Euphausia superba...
