The absorbance of the reaction mixtures was measured using a spectrophotometer at 765 nm wavelength after incubation for 2 h at room temperature. Gallic acid was used for calibration of the standard curve and total phenolic content was expressed as milligram gallic acid equivalent per gram ...
Enantioselective synthesis without any chiral auxiliaries or chiral catalysts is rare, particularly when remote stereogenic centers are involved. Here, the authors report on enantioselectivity of heterochiral coupling in the one-pot reaction of racemic hydrazides with achiral 1,4-bis(isothiocyanine)benzene...
reaction to ninhydrin and Folin–phenol reagents. Moreover, it had a molecular weight of approximately 7 kD and was nondializable and heat stable. It was concluded that the oviposition stimulant was proteinaceous and,Arthuret al.(1973) were successful in stimulating similar oviposition activity ...
- namely, one in which protons are transported from the matrix to the intermembrane space; a second in which protons are transferred back into the matrix in conjunction with the synthesis of ATP; and a third wherein protons re-enter the matrix without being coupled to any chemical reaction....
A portion (1 μL) of each cDNA sample was amplified in a 20 μL PCR reaction, including 0.5 μL of upstream and downstream primers, 10 μL of 2 × Fast qPCR Master Mixture (Green), and ddH2O was added to a final volume of 20 μL. The Line-Gene 9600 Plus real-time PCR ...

The presence of soft, dispersed interface-rich structures leads to not only selective reaction accelerations but also changes in reaction pathways, whereby chemical reactions are guided towards desired products. Once again, the analogy to enzyme-catalysed transformations is enticing. In this Review, we...
and water was set to run through the condenser to ensure cooling. The extraction was allowed to undergo its reverse flow for exactly 2 h, after which it was stopped. The quantity of crude fat oil (in percentage) present in the sample was obtained by deducting the initial weight from the ...
