Eleven compounds were isolated from potato peels and identified. Their structures were determined by interpretation of UV, MS, 1D, and 2D NMR spectral data and by comparison with reported data. The main components of the potato peels were found to be chlorogenic acid and other phenolic compounds,
Colneleic acid is an unsaturated ether fatty acid derived from linoleic acid via a lipoxygenase-mediated enzyme pathway. It is degraded (a) by an enzyme in potato tubers which is heat-labile and non-dialysable and (b) by a model system containing catalytic amounts of Fe(2+) ions. Both enzyme- and
The dose response for elicitation of the hypersensitive reaction in potato tuber discs by arachidonic acid (AA) suggested saturation at higher concentrations. Glucans from Phytophthora infestans, inactive themselves as elicitors of the hypersensitive reaction, enhanced sesquiterpene accumulation and
Eicosapentaenoic and arachidonic acids extracted from the fungus Phytophthora infestans elicit the accumulation of fungitoxic sesquiterpenoid stress metabolites and inhibit the accumulation of steroid glycoalkaloids in potato tubers. This dual activity, which did not occur with other saturated and
The influence of storage duration on the lipid and fatty acid content of potato tubers and on the concentration of volatile aroma substances in potato chips were studied. An increase in the unsaturated fatty acids of potato tubers was found during the first months of storage. The higher lipid
Eicosapentaenoic and arachidonic acids in extracts of Phytophthora infestans mycelium were identified as the most active elicitors of sesquiterpenoid phytoalexin accumulation in potato tuber slices. These fatty acids were found free or esterified in all fractions with elicitor activity including
A sweet potato-based Meal Replacement Seeds Juice (MRSJ) was developed by mixing sweet potatoes and carrots with four types of seeds. Consuming the MRSJ rather than the whole vegetables or whole seeds improved digestive function, proving that it is suitable for the elderly. Its rich composition of
Atherosclerosis is a chronic pathological process and it is generelly accepted that lipids, coagulation and inflammatory factors play an important role in its development. Environmental factors such as bed diet and cigarette smoking strongly stimulate initation and progression of atherosclerotic
Potato protein (PP) has promising potential for utilization in food applications due to its high nutritive value and functional properties. Grapeseed oil (GO) is rich in unsaturated fatty acids and antioxidant active ingredients. However, its application is limited because of low We report the expression profile of acyl-lipid Delta12-desaturase (desA) gene from Synechocystis sp. PCC6803 and its effect on cell membrane lipid composition and cold tolerance in prokaryotic (Escherichia coli) and eukaryotic (Solanum tuberosum) cells. For this purpose, a hybrid of desA and
Recently, transgenic potato plants were created with overexpression of the 14-3-3 protein derived from Cucurbita pepo. Detailed analysis of those plants suggested that the function of the isolated 14-3-3 isoform is in the control of carbohydrate and lipid metabolism in the plants. 14-3-3 protein
In order to verify the role played by oxidation in the budding of potato tubers (Solanum tuberosum L. cv. Kennebec), the physiological events occurring below bud at 4 degrees C have been studied for a period of 6 months. The low temperature storage induced an increase in the degree of unsaturation
Stearoyl-acyl carrier protein desaturase (SAD), locating in the plastid stroma, is an important fatty acid biosynthetic enzyme in higher plants. SAD catalyzes desaturation of stearoyl-ACP to oleyl-ACP and plays a key role in determining the homeostasis between saturated fatty acids and unsaturated
The search for efficient oleaginous microorganisms, which can be an alternative to fossil fuels and biofuels obtained from oilseed crops, has been going on for many years. The suitability of microorganisms in this regard is determined by their ability to biosynthesize lipids with preferred fatty
Snack foods can contribute a high proportion of energy intake to the diet. Peanuts are a snack food rich in unsaturated fatty acids, protein and fibre which have demonstrated satiety effects and may reduce total energy intake, despite their high energy density. This study examined the effects of
