Ethane production by homogenates of Phaseolus vulgaris L. cv. Harvester was studied. The precursor of ethane was identified as linolenic acid. The liberation of ethane was optimum at pH 4.2 and was highest from homogenates of leaves and apical buds. When roots were homogenized in linolenic acid solution, ethane and ethylene production were stimulated. In corn root homogenates, ethylene biosynth...

Background— -Linolenic acid may protect against cardiovascular disease. We examined the association between adipose tissue -linolenic acid and nonfatal acute myocardial infarction (MI) in a population-based case-control study in Costa Rica. Methods and Results—The 482 case patients with a first nonfatal acute MI and 482 population control subjects were matched by age, sex, and area of residence...

The effect of oleic, linoleic and γ-linolenic acids on ROS production by 3T3 Swiss and Rat 1 fibroblasts was investigated. Using lucigenin-amplified chemiluminescence, a dose-dependent increase in extracellular superoxide levels was observed during the treatment of fibroblasts with oleic, linoleic and γ-linolenic acids. ROS production was dependent on the addition of β-NADH or NADPH to the medi...

Brassica napus leaves developed at low temperature display rapid in situ desaturation of monogalactosyldiacylglycerol (MGDG) fatty acids leading to the production of hexadecatrienoic/linolenic acid. This was shown by radioactivity-tracer experiments to occur via a sequence of desaturations proceeding from the initially synthesized palmitic/oleic acid molecular species to palmitic/linoleic acid,...

In both plants and animals pathways exist for the conversion of oleic acid to polyenoic acids (1, 2), but these pathways lead to different end products in the two kingdoms. In green plants the double bond system is extended toward the methyl end of the molecule to form linoleic and linolenic acids (9,12, lBoctadecatrienoic acid) (1,3,4). The ciliated protozoa, the amoebae, and some other animal...

boraginaceae family is known as a medicinal plant classified in dicotyledons.  it is originated from asia (middle east). the aim of this study was to evaluate ingredient between 4 species of boraginaceae family based on physiological & phytochemical traits as well as seed fatty acid contents.  4 species (e. russicum, e. italicum, e. amoenum, and b. officinalis ) were evaluated carefully. all se...

In the time period of 1994–1998, a case-control study on diet and prostate cancer was carried out in Uruguay to examine the risk associated with fat intake. Two hundred and seventeen (217) incident cases afflicted with advanced prostate cancer were frequency-matched with 431 controls on age, residence, and urban/rural status. The analysis was carried out using unconditional multiple logistic re...

Background— -Linolenic acid, an intermediate-chain n-3 fatty acid found primarily in plants, may decrease the risk of fatal coronary heart disease (CHD) through a reduction in fatal ventricular arrhythmias and sudden cardiac death (SCD). Methods and Results—We prospectively examined the association between dietary intake of -linolenic acid assessed via updated food-frequency questionnaires and ...

Azadirachta indica, is locally called as “Neem” belongs to the family Meliaceae. “Neem” is a medicinal herb traditionally used for the treatment of Diabetes, leprosy and Respiratory diseases. The present study was carried out to identify the phytocomponents present in the methanolic extract of the leaves of Azadirachta indica by GC-MS analysis. From the GC-MS results five compounds were identif...

After 7 days of germination in the dark, the three sections of pea seedlings studied (cotyledons, stems, and young leaves) are rich in linoleic acid; after illumination of the seedlings a very significant increase in linolenic acid is observed in the young leaves section, whereas only small variations are noted in the fatty acid composition of the other sections. The increase in linolenic acid ...
