in this research, after carrying out chemical tests measuring the moisture, protein and ash contents on rice flour according to standard methods, gluten- free breads were prepared from rice flour combined with 0.5% carboxy methyl cellulose (cmc) and 1% -κcarrageenan gum. a sample lacking gum was also produced as control. rice breads (with gum and without gum) were then produced by semi-industri...

Reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. Substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methy...

The hypothesis that the last step in the biosynthesis of 4,7,10,13,16,19-22:6 from linolenate is catalyzed by an acyl-CoA-dependent 4-desaturase has never been evaluated by direct experimentation. When rat liver microsomes were incubated with [1-14C]7,10,13,16,19-22:5, under conditions where linoleate was readily desaturated to 6,9,12-18:3, it was never possible to detect the product of the put...

methyl tetra - 0-methyl- ?-d- glucopyranoside is stereoselectively prepared from tetramethyl-d- glucopyranose by using (mei+nah) in toluene (86%) or cyclohexane (85%), while its ?- isomer is best synthesized in hexamethyl phosphoramide (64%). similarly, methyl tetra-o-methyl-?- d-mannopyranoside is synthesized in cyclohexane (80%), while its ?- isomer is predominantly prepared by (mei+n-buli) i...

Reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-SiO2/HClO4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1H-pyrazol-5-ol derivatives in high yields.
