SUMMAR,Y Incubation of human serum solutions low in glyceride content for 16 hr resulted in a net increase of cholesterol esters in all three major human serum lipoprotein classes, namely the very low-density lipoproteins of d < 1.006 (VLDL), low-density lipoproteins of d 1.006-1.063 (LDL) and highdensity lipoproteins of d 1.063-1.21 (HDL). Transfer of glycerides from the VLDL to the LDL and HD...

The methyl esters of carboxylic acids are characteristic olfactory volatile compounds for the sweet aroma of snake fruit, (Salacca edulis, Reinw) cv. Pondoh. Although methanol was not detected as a volatile constituent, the crude enzymes showed activity to synthesize the methyl esters in the presence of acyl-CoA and methanol. Therefore, the biosynthetic origin of methanol was investigated, resu...

the seed of croton tiglium l. (sct) is a well known folk medicine. in china, it has used to treat gastrointestinal disorders, intestinal inflammation, rheumatism, and so on. previous studies established its purgative and inflammation properties. in addition, the effects of essential oil of sct on intestinal transit and gastrointestinal tract has been studied. in the present study, we evaluated ...

Esters of 2-iodoxybenzoic acid (IBX-esters) are potentially valuable oxidizing reagents belonging to a new class of pentavalent iodine compounds with a pseudo benziodoxole structure.

zn/acoh on silica gel converts a range of structurally different sulfoxides to their corresponding thioethers in excellent yields under microwave irradiation. it has been found that chemoselective deoxygenation of sufoxides can be achieved in the presence of other reducible functional groups such as acetals, acids, amides,   esters, ketones and nitriles.

The ionization and fragmentation patterns of 24 compounds with elemental composition CmH2mO2, including isomeric esters alkanoic acids, were investigated by atmospheric pressure corona discharge collision-induced dissociation (CID) mass spectrometry in the positive-ion mode. All ionized as protonated molecules NH4+ adducts. In addition, fragment ions observed spectra other than methyl esters, w...

silica chloride converted benzyl or tert-butyl esters to the corresponding acid chlorides and alkyl chlorides. it also converted benzyl or tert-butyl phenyl ethers to the corresponding allcyl chlorides and phenol

the adducts produced in the reaction between trialkyl phosphites and acetylenic esters were trapped by hydantoins to produce highly functionalized dialkyl 2-(2,5-dioxo-4,4-diphenylimidazolidin-1-yl) succinate in good yields.

BACKGROUND The purpose of this study was to select appropriate surfactants or blends of surfactants to study the ternary phase diagram behavior of newly introduced palm kernel oil esters. METHODS Nonionic surfactant blends of Tween(®) and Tween(®)/Span(®) series were screened based on their solubilization capacity with water for palm kernel oil esters. Tween(®) 80 and five blends of Tween(®) ...

Organoboron chemistry has been widely explored and developed in synthetic for over half a century provides various elegant protocols polymer synthesis. Compared with most trivalent bare organoboron compounds, N-coordinated shows better performances, such as air moisture stability. This review summarizes the application of boranes boronic acid/esters synthesis materials science. We introduce sig...
