Specific accumulation of docosahexaenoic acid (22∶6n−3) in brain lipids during development of juvenile turbot Scophthalmus maximus L.
Abstract The changes in the lipid class and the fatty acid compositions of total lipids and individual glycerophospholipids which occur in brain during development of juvenile turbot ( Scophthalmus maximus L.) were investigated. Fish were sampled during a 10‐week period immediately following weaning...
