Quantitative high‐resolution 13 C and 1 H nuclear magnetic resonance of ω3 fatty acids from white muscle of atlantic salmon ( Salmo salar)
Abstract High‐resolution 13 C nuclear magnetic resonance (NMR) spectra have been obtained and used to define the ω3 (n‐3) fatty acid distribution in lipid extract and white muscle from Atlantic salmon ( Salmo salar ). The 13 C spectrum of lipid extracted from muscle gives quantitative information ab...
