Lipid composition of the liver oil of the ray, Himantura bleekeri
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Nechet, Sandrine; Dubois, Nolwenn; Gouygou, Jean-paul; Berge, Jean-pascal.
If rays are traditionally fished for their caudal fins, the rest of the body is wasted, except part of the skin that can be transformed into leather. Liver oil of the ray, Himantura bleekeri, was characterized in terms of lipid class composition and fatty acid profile. Liver oil content was high and represented 54% of the liver weight (w/w). Neutral lipids were predominant (92%), major components being triacylglycerols (63%). Other neutral lipids identified were hydrocarbons, sterol esters, mono- and di-acylglycerols, free fatty acids, sterols and glyceryl ethers. Polyunsaturated fatty acids of the n-3 series, namely eicosapentaenoic and docosahexaenoic acids, were high (4% and 16%, respectively). Cholesterol was the major component in the sterol fractions...

Remodeling of membrane lipids in gills of adult hard clam Mercenaria mercenaria during declining temperature
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Parent, G; Pernet, Fabrice; Tremblay, R; Sevigny, J; Ouellette, M.
In a previous study, a major remodeling of lipids, consistent with the theory of homeoviscous adaptation, was observed in the juvenile hard clam Mercenaria mercenaria during a temperature reduction from 24 to -1 degrees C. In addition, the lipid remodeling varied between genetically distinct lines of hard clams. The present study examined whether adult hard clams originating from different locations and a selectively bred variety show differences related to their genetic characteristics in the remodeling of lipids that normally occur during decreasing temperatures. Wild hard clams from 4 locations in Atlantic Canada and the selectively bred M mercenaria var. notata were held at an aquaculture growout site located at the northern distribution limit of the...

Lipid composition of the pacific lion-paw scallop, Nodipecten subnodosus, in relation to gametogenesis - 2. Lipid classes and sterols
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Palacios, Elena; Racotta, I.s.; Arjona, O; Marty, Y; Le Coz, Jean-rene; Moal, Jeanne; Samain, Jean-francois.
Knowledge on the energy distribution during the reproductive cycle of the giant lion-paw scallop, Nodipecten subnodosus is limited, but necessary for aquaculture purposes. In a previous work, we found that natural food availability can sustain the full cost of gametogenesis in optimal environmental conditions. The present study analyses the lipid and sterol classes' composition of several tissues during gametogenesis. In female gonads, the quantity of triacylglycerol (TG) increased parallel to gametogenesis from December (spawned gonads, 0.7 mg g(-1) or 7% of total lipids) to June (ripe gonads, 52 mg g(-1) or 66% of total lipids). In male gonads sampled in June, the concentration of TG (0.7 mg g(-1) or 3.5% of total lipids) and esterified sterols was...

การเปรียบเทียบกลุ่มสาร Acylated Steryl Glucosides  ในข้าวกล้องและข้าวกล้องงอก และความสัมพันธ์กับสีของข้าว

Acylated Steryl Glucosides (ASGs) are unsaponified matters distributed ubiquitously in edible plant sources including brown rice. ASGs in pre-germinated brown rice have reported to improve insulin activity and blood glucose control mechanisms in the diabetic condition through the activation and increasing of insulin like growth factor 1 (IGF-1) production. Alleviating symptoms of both diabetes and pre-diabetes of dietary intake of brown and pre-germinated brown rice has well known. To improve the functional dietary intake of Thai rice, identification of ASGs in seven varieties, namely: Khao Dawk Mali 105, PTT1, RD31, Sangyod, RD6, Niaw Dam Chum Pae and Niaw Dam Maw, brown and pre-germinated were carried out. Firstly, extracted sample of brown and...

Dietary intake of pre-germinated brown rice has been reported as alleviating symptoms of diabetes and pre-diabetes. Later, the corresponding bioactive compound was identified as Acylated Steryl Glucosides (ASGs) which was found to be a bioactive substance that may affect pancreatic-cells through the activation of insulin like growth factor 1 (IGF-1) dependent mechanisms in the diabetic condition. To improve the functional dietary intake of Thai rice, identification of ASGs in seven varieties, namely: Khao DawkMali 105, PTT1, RD31, Sang yod, RD6, Niaw Dam Chum Pae and Niaw Dam Maw, brown and pre-germinated Thai rice varieties were carried out. Brown and pregerminated rice were analyzed to search for ASGs using GC-MS to identify the sterol moieties, and...

Acylated Steryl Glucosides (ASGs) are unsaponified matters that are ubiquitously distributed in edible plant sources, for example barley, maize and brown rice. ASGs in pre-germinated brown rice have reported to improve insulin activity and blood glucose control mechanisms in the diabetic condition through the activation of insulin like growth factor 1 (IGF-1) and increasing of IGF-1 production. Recently, the medical studies confirm that dietary intake of brown and pre-germinated brown rice is useful for alleviating symptoms of both diabetes and pre-diabetes. To improve the functional dietary intake of Thai rice, identification of ASGs in seven varieties, namely: Khao Dawk Mali 105, PTT1, RD31, Sang Yod, RD6, Niaw Dam Chum Pae and Niaw Dam Maw, brown and...

Changes in lipid profile during growth and senescence of Catharanthus roseus leaf
Provedor de dados: Brazilian Journal of Plant Physiology
Autores: Mishra,Sanjay; Tyagi,Abhishek; Singh,I.V.; Sangwan,R.S.
Various lipid classes and compounds were monitored during the period of leaf emergence to leaf drop of Catharanthus roseus. The expansion to early maturation phase was accompanied by cellular build-up of all major lipid classes, whilst aging and senescence were characterized by their substantial decline, except for the neutral lipids; the leaf monogalactosyl diglyceride/digalactosyl diglyceride ratio decreased from 4.3 (complete maturity) to 2.1 (abscised stage). The early maturation stage was the earliest stage when appreciable amounts of free sterols and fatty acids could be observed. Sterol/phospholipids ratios increased by 68-fold in the abscised leaf as compared to that at full maturity. The unsaturated/saturated fatty acid ratio was far lower in the...
