It has previously been shown that the hydrolysis of high density lipoprotein (HDL) phospholipids by hepatic lipase promotes the hepatic uptake of triglyceride and cholesteryl ester from HDL. Since the hydrolysis of HDL phospholipids promotes HDL cholesteryl ester uptake, then it is possible that the hepatic metabolism of HDL could be altered by changing the molecular species composition of HDL ...

A Virginia type peanut mutant with more than 60% oleate content (E2-4-83-12) was selected from an EMS mutagenized population of LF2 (an export type peanut cultivar with 44.2% oleate) by near infrared reflectance spectroscopy. Cloning and sequencing of FAD2B from LF2 and E2-4-83-12 identified a novel mutation (C313T in the coding region) causing an H105Y substitution in the first histidine box o...

Deficiencies in the activity of the microsomal oleoyl phosphatidylcholine (oleoyl-PC) desaturase from peanuts are the basis of the high oleate oil. Mutation of aspartate-150 to asparagine and the attendant decrease in activity, together with the loss in expression of the higher activity transcript, was the molecular basis of the high oleate trait. The ability of oleoyl-PC desaturase to desatura...

glycerol mono-oleate (gmo) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of cofe2o4 nano-particles by surfactant-assisted microwave method. fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and...

Allele-specific PCR (AS-PCR) with 3 primers was used to identify true F1 hybrids resulting from normal oleate groundnut cultivars pollinated with high oleate groundnut genotypes with a 1-bp insertion (A:T) at position 442 after the start codon in FAD2B. Its reliability was confirmed by direct sequencing of FAD2B PCR products. The AS-PCR protocol requires minimal resources, and thus provides an ...

The effects of pancreatic hormones and cyclic AMP on the induction of ketogenesis and long-chain fatty acid oxidation were studied in primary cultures of hepatocytes from fetal and newborn rabbits. Hepatocytes were cultivated during 4 days in the presence of glucagon (106 M), forskolin (2 x 10'M), dibutyryl cyclic AMP (10-' M), 8-bromo cyclic AMP (10-' M) or insulin (10-' M). Ketogenesis and fa...

The capacities of certain compounds at pH 7.3-7.5 to inactivate the virus of lymphocytic choriomeningitis have been demonstrated. Among the more effective substances were the fatty acids chaulmoogric, linolic, linolenic, myristic, oleic, and ricinolic, and the detergents zephiran, duponol LS, and aerosol OT. Upon the oleic acid inactivation of the virus, studies have been made of such variables...
