Bromine-substitution at an aliphatic carbon generally gives rise to the primary or secondary loss of hydrogen bromide (HBr), e.g., via a 1,2-elimination or otherwise. In positive-ion mode, 2-Bromo-2-ethylbutanamide ([M+H]+ with m/z 194.0175; [C6H13BrNO]+) shows a primary loss of...
Although various hypotheses and models were proposed in the literature, the nature and the mechanism of DNA mutations are not quite clear yet. Any changes in the DNA sequence, the key to all genetic information, can generate mutations during the replication or repair processes. Therefore, ...
Nyon, Switzerland - The global market for amine catalysts for polyurethanes will reach a volume of nearly 55 kilotonnes by 2016, and have a value of 350 million, at present exchange rates, according to a market report on the sector by Swiss-based consultant Dr Joop Koster. 年份: 2007 收藏...
Although we observed BSH amineN-acyltransferase activity with both CA and TCA, the conjugation mechanism is unclear. On the basis of the known mechanistic details of BSH’s hydrolytic activities and it belonging to the N-terminal nucleophile superfamily of enzymes, the terminal cysteine Cys1ofBlBSH...
peptidyl-glycylleucine-carboxyamide, nisin, carvacrol, and cinnamon, which were associated with the disruption and depolarization of the cell membrane, and detrimental effects on the cell wall integrity34,35,36. These results suggest that the three SMs might interact with theSalmonellacell membrane an...
By this mechanism, they reduce intracellular Ca2+ activity and interfere with the replenishment of Ca2+ stores in vascular smooth muscle. Tonic and phasic muscle contractions are depressed in a dose-dependent manner. The various types of voltage-dependent Ca2+ channels include L, N, T, P/Q, ...
water solution saturated with CO2, which can enhance their foaming ability and foam stability, and the foaming ability can be switched off or on by CO2 or replacing with N2 with heating, so the amine-surfactants have great potential for smart mobility control to gas channeling during CO2 ...
