  • Title: Composition of phospholipids of white muscle of six tuna species.
    Author: Medina I, Aubourg SP, Pérez Martín R.
    Journal: Lipids; 1995 Dec; 30(12):1127-35. PubMed ID: 8614303.
    Abstract:
    A comparative study of the phospholipids of white muscle of six of the commercially utilized tuna species, including quantitative analyses of phospholipid classes and studies of the acyl composition of the major components. Plasmalogen compounds also were identified and quantified. Choline and ethanolamine glycerophospholipids were the most abundant classes in all the samples, as well as the only molecules containing plasmalogens (16:0, 18:0, and 18:1 alkenylether chains). The patterns of fatty acid distribution within each of the phospholipid classes showed general similarities in the species analyzed. However, ratios between certain saturated and polyunsaturated fatty acids in different phospholipid classes showed remarkable differences. The high content of n-3 polyunsaturated fatty acids in the principal phospholipids, such as the plasmalogens, and taking into account the fatty acids possible importance in human nutrition, indicates that the white muscle of tuna species may be a potentially important dietary item.
