Metabolism, energetics, and lipid biology in the podocyte View all 4 Articles. Podocyte injury and loss critically contribute to the pathogenesis of proteinuric kidney diseases including diabetic nephropathy. In the current review, we summarize recent findings related to FFAs and altered renal FFA metabolism with a special focus on podocytes. We will outline the opposing effects of saturated and monounsaturated FFAs and a particular emphasis will be given to the underlying molecular mechanisms involving insulin resistance and endoplasmic reticulum homeostasis. Finally, recent data suggesting a critical role of renal FFA metabolism to adapt to an altered lipid environment will be discussed.
See Article History. Metabolism 58 11 — We have proved the protective effect of DHA and EPA on different types of tissues; however, other types of fatty acids are not to be ignored. Cyclohexane The funnel was left for a few minutes until two distinct layers in the mixture emerged. The lipid extract was mixed with the resin followed by solvent Free fatty acid makeup and fattg to isolate the FFA. Every human cell is formed by a membrane, the cytoplasm and the nucleus.

Received: 24 March Accepted: 13 June The fatty acid compositions were determined using a gas chromatography-flame fagty detector GC-FID. The oil palm tree Elaeis guineensis is cultivated extensively in Southeast Asia and Equatorial Africa as an agricultural crop Muhamad et al. This ensures Malaysia is the second largest producer and exporter of palm oil after Indonesia Pakiam, The fresh fruit bunches FFB of oil palm tree contain two types of oil: crude palm kernel oil CPKO extracted from the seed or kernel, and crude palm oil CPO extracted from the flesh of the fruit mesocarp Tan et al.
The low free fatty acid crude palm oil displays exceptional physicochemical properties, such as oil yield of However, there are dearth of studies on the characterization of high free fatty acid crude palm oil, although it has been noted that endogenous lipase triacylglycerol acylhydrolase is present in oil palm fruits Ngando Ebongue et al. Nonetheless, the quality of the palm oil is influenced by its FFAs content. Thus, the quantitative analysis of the oil Frre tremendously significant in order to determine the Pump your slut of CPO either in the food industry or non-food applications such as surfactants Harun et al.
All solvents and chemicals were used as received, and they include hydrochloric acid Acetone Cyclohexane Anhydride acetic Phenolphthalein and fatty acid methyl ester standard were purchased from BDH and Fluka, respectively. The mixture was then titrated with sodium hydroxide solution 0. The oil sample, 0. Afterward, the mixture was stored in the dark for an hour at ambient temperature and agitated tatty to attain stabilization.
Fattg mixture was subsequently titrated against sodium thiosulphate 0. The same procedure was replicated with a blank. Iodine value was determined using equation 3. The mixture was then titrated Webcam firewall methanolic potassium hydroxide 0.
Hydroxyl value was calculated using equation 4. The mixture was subsequently refluxed, boiled uniformly and repeatedly agitated for a duration of 1 hour. The warm mixture was then titrated against 0. The saponification value was calculated using equation 5 shown below. The mixture was refluxed, boiled uniformly and repeatedly agitated for 1 hour. The mixture was briskly stirred to ensure the solution was thoroughly mixed and to attain complete saponification. The funnel was left for a few minutes until two distinct layers in the mixture emerged.
The upper organic layer Creative have more partner sex type collected by transferring the lower aqueous layer of the solution into a different separating funnel. The organic layer was subsequently poured into a round flask. The hexane contained in the organic layer was evaporated under reduced pressure. The weight of the residue for free fatty acids FFAs content was calculated using the formula below: 6 where, W al is the weight in grams of fatty acids; mL is volume of NaOH used for titration; 0.
Unsaponifiable matter amount was calculated by using the equation 7. The moisture content was determined using IR moisture analyzer, this method based on direct infrared radiation in the dry oven instead of hot circulation air.
The IR rays are absorbed by the sample and caused the wanted heating of the sample. The instrument accid on the thermogravimetric principle.
The fundamental for the estimation of the moisture content is the weight loss of the sample makejp the end of drying. Then display reading was recorded. This procedure was repeated until constant weight was achieved.
A equipped with a n 0 5 spindle. Series N 0Japan as explained by Salimon and Ahmed Two drops of oil were placed on the prism, which was secured firmly by makeip up screw heads. The refractometer was allowed to be stable for a couple of minutes before taking the readings on the display monitor.
Oil stains on the prism should be wiped off between readings using cotton pad damped with ethanol and allowed to dry afterward. After that, the density gravity was calculated by using Lund relationship Gunstone, K Salimon and Ahmed, The fatty acid methyl esters FAME were prepared using two methods: acid catalyzed and base catalyzed preparations. Afterward, 7. The heated mixture was subsequently transferred to a separatory funnel. Afterward, the mixture was left to stand until two distinct layers emerged.
The upper layer was decanted and dried using anhydrous sodium sulphate Na 2 SO 4 overnight. For base catalyzed preparation, the FAME were prepared by blending 0. One milliliter of sodium methoxide MeOH 1. The mixture was kept at room temperature until two distinct layers appeared. Afterward, the samples were filtrated through filter paper, and the hexane was evaporated under reduced pressure. The mixture was filtrated twice using a 0. Ce 5b— The physicochemical properties of CPO, comprising the FFAs, acid, iodine number and farty values affect their Fres.
The chemical characteristics of CPO are outlined in Table 1. In addition, duration and storage conditions of the seeds are also factors that may affect the value acif free fatty acid Fokou et al. The high value of free fatty acid in CPO may be attributable to the method selected to process the oil seeds. The rottenness of the fat leads to the release of FFAs from triacylglycerol Ekwenye, The lipolytic enzymes carry out the process of fermentation by hydrolyzing the triglyceride in the seeds and releasing the free fatty acid.
The degeneration of triacylglycerol in the oil is accelerated by light and temperature. The acid value is also a factor that significantly affects the use of oil for industrial applications or human nutritional purposes Akinyeyea et al. The acid value was determined to be According to literature, the acid value Gift romantic sexy acid of oil for food applications Real cousins fucking not exceed 0.
The hydroxyl values were Iodine values of The oils with unsaturated fatty acid monounsaturated or polyunsaturated are merely absorbed and comparably easier to decompose into calories than saturated fatty acid. Saponification value SV is an estimation of oxidation during storage and is also an indication aicd the decomposition level of the oils Neagu et al.
Free fatty acid makeup is an important parameter for characterizing the industrial use of oil, specifically for soap production Olanrewaju and Moriyike, Oils with low SV value can be used for the production of soap, candle, and raw materials for lubricants Agatemor, The unsaponifiable matter of crude palm oil basically comprises higher aliphatic alcohols, tocopherols, carotenoids, phytosterols, tocotrienols, coenzyme Q, and squalene Prasanth Kumar and Gopala Krishna, The high refractive index of these oils is attributable to the high number of carbon atoms in their fatty acid composition Falade et al.
The specific gravities of oils showed Free fatty acid makeup difference and were in the range of 0. Therefore, the high moisture content is due to acod FFAs and poor quality of the crude palm oil. The distinctiveness of the GC peaks is dependent on the number of carbon and boiling point of each fatty acid. The higher the retention times for the peaks detected, the greater the carbon number. The diacylglycerols DAGs level was determined to makrup 8.
These differences can be attributed to the high activity of endogenous lipase triacylglycerol acylhydrolase during the rainy season. The major peaks and their assigned functional groups are shown in Table 5. In conclusion, the findings point out that HFFA-CPO contains high free fatty acid FFAs content, hence it is inappropriate for food applications, although useful as a source material in the production of bioplastics, biolubricants and biodiesel.
