TL;DR: In this article, castor oil was alcoholyzed with both aliphatic alcohols, such as glycerol and pentaerythritol, and an aromatic alcohol, bisphenol A propoxylate.
Abstract: In this study, castor oil was alcoholyzed with both aliphatic alcohols, such as glycerol and pentaerythritol, and an aromatic alcohol, bisphenol A propoxylate. The resulting alcoholysis products were then malinated and cured in the presence of styrene. Soybean oil pentaerythritol glyceride maleates were also prepared for a direct comparison of the properties of the castor oil and soybean oil based resins. Castor oil was directly malinated as well to see the effect of the alcoholysis step on the properties of the castor oil based resins. The monomers synthesized were characterized by 1 H-NMR spectroscopy, and the styrenated resin liquid properties, such as viscosity and surface energy values, were determined. The conversion of polymerization was determined using time resolved FTIR analysis for the styrenated soybean oil pentaerythritol glyceride maleates, castor oil maleates, and castor oil pentaerythritol glyceride maleates. The effect of monomer identity and styrene content on the conversion of polymerization was explored.

TL;DR: The effects of dietary lipid sources on the growth response of hybrid tilapia and enzymic lipid peroxidation in the sarcoplasmic reticulum of these fish fed different dietary lipids was studied.
Abstract: The effects of dietary lipid sources on the growth response of hybrid tilapia (Oreochromis niloticus×O. aureus) were investigated. Enzymic lipid peroxidation in the sarcoplasmic reticulum (SR) of these fish fed different dietary lipids was also studied. Experimental fish were given diets containing no additional lipids (control), lard, soybean oil, menhaden fish oil and methyl esters of n-3 highly unsaturated fatty acids (HUFA) for 10 weeks. There was no difference in survival rates among test groups. Compared to fish supplied with dietary lipids, fish consumed control diet with trace lipids (0.02%) were low in final body weights and muscle lipids. The specific growth rates and weight gains of fish fed soybean oil and fish oil were significantly higher than other groups (P<0.05). Fatty acid compositions of muscle and SR reflected the fatty acid compositions of dietary lipids. The thiobarbituric acid reactive substances produced by iron catalyzed NADH-dependent lipid peroxidation were significantly different (P<0.05) among SR isolated from fish fed different dietary lipids. Lipid peroxidation activity of HUFA group was the highest, followed by fish oil, soybean oil, lard and control group.

TL;DR: Significant differences in carcass moisture and lipid contents of carcass and liver were observed among fish fed the dietary treatments and generally, the fatty acid composition of fish fillets and livers reflected the dietary FA composition.

TL;DR: It has been demonstrated that immersing pretreatment of lipase in oils could improve both the reaction rate and methyl ester yield significantly, and it has been proposed that Immersing Pretreatment of Lipase in Oil contributes to improvement in enzyme activity.
Abstract: When crude soya-bean oil was used as the source for biodiesel production, the yield of methyl ester was significantly lower than that from refined soya-bean oil. The major difference between refined and crude soya-bean oils was found to be due to the contents of phospholipids, free acid and water, which have varied influences on biodiesel production. Phospholipid content was the most influential factor; the higher the phospholipid content in the oil, the lower is the methyl ester yield. The optimal water activity was found to be in the range 0.12-0.44, and free acid included in crude soya-bean oils showed no negative effect on enzymic transesterification. During our study of three-step methanolysis of crude soya-bean oils for biodiesel production, we noted that the second-step methanolysis was much faster than the first-step reaction. On the basis of this finding, the proposal that immersing pretreatment of lipase in oils contributes to improvement in enzyme activity has been put forward. In addition, it has been demonstrated that immersing pretreatment of lipase in oils could improve both the reaction rate and methyl ester yield significantly. A methyl ester yield of 94% could be achieved by immersing lipase in crude oils for 120 h and this was just as high as the yield for refined oils.
