The chemical characterisation and nutritional value of eggs from the five deep-sea sharks leafscale gulper shark (Centrophorus squamosus), greater lantern shark (Etmopterus princeps), longnose velvet dogfish (Centroscymnus crepidater), Portuguese dogfish (Centroscymnus coelolepis) and black dogfish
Changes in the quantitative composition of triacylglycerols (TAGs) in maturing sea buckthorn (Hippophaë rhamnoides L.) seeds were determined by lipase hydrolysis. As a whole, the rate of synthesis of separate TAG classes increased in proportion to both their unsaturation and relative content (weight
Sea buckthorn seed oil (SBSO) has been used as a functional food in the prevention of heart diseases. The present study investigates the effects of SBSO on blood cholesterol and the gut microbiota in hypercholesterolemia hamsters. Four groups of hamsters (n = 8 each) were given one of four diets,
Phosphatidylcholine content in the spermatozoa of the sea urchin, Hemicentrotus pulcherrimus, decreased rapidly during incubation with sea water. Sea urchin sperm contained approx. 85% phospholipid in total lipid. Phosphatidylcholine (PC) was the principal lipid. Other phospholipids, however,
The aim of the present study was to determine the influence of the dietary fatty acid profile on the lipoprotein composition in sea bream fed different vegetable oils. Six experimental diets were formulated combining fish oil with three vegetable oils (soybean, rapeseed, linseed) in order to obtain
Despite the good growth performance of several fish species when dietary fish oil is partly replaced by vegetable oils, recent studies have reported several types of intestinal morphological alterations in cultured fish fed high contents of vegetable lipid sources. However, the physiological process
BACKGROUND
Epidemiological studies indicate beneficial effects of flavonoids on cardiovascular disease (CVD) risk.
OBJECTIVE
To study the effect of flavonoid-rich sea buckthorn berry (SBB) on circulating lipid markers associated with CVD risk and plasma flavonol concentration. Also investigated was
The chemical composition of yolk lipoproteins (YLP-1, 2, and 3) was determined. YLP-1, 2, and 3 were quite similar as regards the chemical composition of lipids, proteins, and carbohydrate moieties. Each lipoprotein has an average dry weight composition of lipids (55--72%) and apo-lipoproteins
The triacylglycerol (TAG) response to fatty meals containing dried and crushed berries or berry extraction residues was studied in a postprandial cross-over study with healthy normal-weight male volunteers. The berry material included sea buckthorn berries, sea buckthorn CO₂ extraction residue
Fatty acid compositions of polar lipids and triacylglycerols isolated from eggs of the sea urchin, Arbacia punctulata, were examined before and 15 min after insemination. The main fatty acids present in polar lipids and triacylglycerols were palmitate, palmitoleate, eicosaenoate, arachidonate and
Neutral and polar lipids in the soft parts of a gastropod species, Ifremeria nautilei, collected from deep-sea hydrothermal vents, were examined to assess the trophic relationships in hydrothermal vents. The vent gastropod obtains many of its lipids from symbiotic chemosynthetic microorganisms. The
Berries and seeds of two subspecies (ssp. sinensis and mongolica) of sea buckthorn (Hippophaë rhamnoides L.) were compared in terms of triacylglycerols, glycerophospholipids, tocopherols, and tocotrienols. The berries of ssp. mongolica contained less oleic acid (4.6 vs 20.2%, p < 0.001) and more
Triacylglycerols (TAGs) 16:1(n-7)/16:1(n-7)/18:1(n-7) (Po/Po/V) and 16:1(n-7)/16:1(n-7)/18:1(n-9) (Po/Po/O) in pulp/peel oils of various sea buckthorn (Hippophae rhamnoides) subspecies and varieties were separated by reversed-phase high-performance liquid chromatography. The regioisomerism of the
TAG of seeds, berries, and fruit pulp/peel of different subspecies of sea buckthorn (Hippophaë rhamnoides) were analyzed by MS and tandem mass spectrometry (MS/MS). The seeds contained mainly TAG with acyl carbon number (ACN) of 52 with 2-6 double bonds (DB) (20-30%), and TAG of ACN 54 with 3-9 DB
