Investigations on Fish Oils V. Phospholipid Composition of Anguilla vulgaris and Mugil cephalus

Abstract

Aale, Phospholipid-Gehalt Grollk6pfe, Phospholipid-Gehalt The muscle, head and viscera phospholipids of the salt-water eel, fresh-water eel, and salt-water mullet were identified. Lysolecithin, sphingomyelin, phosphatidylserine, lecithin, phosphatidylethanolamine and an unknown phospholipid were quantitatively determined by T.C.L. The total phospholipid contents were found to be in the following increased order: Muscle < head < viscera. Lecithin and cephalins make the two major phospholipids. Phospholipids were found to contain saturated, dienoic, trienoic and tetraenoic fatty acids more than the total lipids. While monoenoic fatty acids percentages are higher in the total lipids.Knowledge on fish oil phospholipids is rather limited when compared to our knowledge on land animals phospholipids. The phospholipid content of fish varies with the genus, the species, the age, the season of the year, and the fish organ. The aim of the present investigation is to study the phospholipid composition of salt-water and fresh-water eel (Anguilla vwlgaris) and salt-water mullet (Mugil cephalus). The fatty acid composition of the fish oil and the phospholipids isolated therefrom were studied. Experimental MaterialsThe saltwater eel (ca. 500 g. each), the fresh-water eel (ca. 600 g. each) and the salt-water mullet (z Kg. each), were caught from Edkou-lake, river-Nile and Al-Manzalah lake, respectively.

Physicochemical Properties, Volatile Compounds and Phospholipid Classes of Silver Carp Brain Lipids

“…PL accounts for 22.73 % of the total lipids. The health benefits and antioxidative behaviors of PLs are intriguing, the content of which in silver carp brain is higher than those in salt water-eel (9.2 %) and mullet Table 1 Physicochemical properties of silver carp brain lipids and other fish lipids muscle (7.0 %), but is considerably lower than that in sardine brain (41.4 %) [27,28]. PC (38.9 %), PE (31.5 %) and PS (13.6 %), most ubiquitous in the PLs of sardine brain, account for 83.9 % of those in silver carp brain [27].…”
