the biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. one of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-coa syn...

objective(s) the liver has major role in the organism homeostasis, interactions with other systems, synthesis and metabolism of bile production, drug detoxification and hormone inactivation. cholestasis can be defined as an impairment of the bile flow which can lead to hepatocytes necrosis and finally cirrhosis. some studies reported a gastric acid secretion reduction in cirrhotic subjects, whi...

background: meat products may be unacceptably tough because of the high connective tissue content of meats used in their manufacture. objective: the aim of this study was using meat acid marination method on some physicochemical and sensory characteristics of beef burgers. methods: meat was marinated in three concentrations (0.5%, 1% and 1.5%) of lactic and citric acid solutions (1:4 w/v) at 4 ...

In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...

novel edible emulsified films were made using pistachio globulin protein (pgp) and palmitic fatty acid at concentrations of 2, 4, and 6 % w/w protein by tween-80 and homogenization technique. addition of palmitic acid to the pgp filmogenic solution resulted in great reduction of wvp in the emulsified films (37-40 %). concentration of palmitic acid did not create significant difference (p>0.05) ...

A gas-liquid chromatography technique which allows simultaneous detection of hippuric acid (N-benzoylglycine) hydrolysis and conversion of fumaric acid to succinic acid by microorganisms uses a new medium, hippurate-formate-fumarate broth, and a gas chromatograph equipped with a thermal conductivity detector. This technique gave more reproducible results than other tests used in the study for d...
