Enzyme rate of reaction measurement equipmentPURPOSE:To enable measurement over a range from a low to high enzyme reaction speed, by providing an optical detection means and first and second computing circuits. CONSTITUTION:Light (c) from a fluorescent tube 2 is directed into a sample container 5...
To govern the reaction rate during continuous transformation of a substrate, the enzymatic activity is regulated by adjusting the potential of the enzyme support so as to transform the substrate at a given rate. The electrode is provided with a particulate enzymatic mass operatively associated with ...
pH effects enzyme activity: The structure of the enzyme has a significant impact on its activity. Changes in the structure of the enzyme, in other words, impact the pace of chemical reactions. The shape and structure of the enzyme will change when the pH of the reaction medium changes. The...
When the substrate solution was filtered before use, very reliable determinations of immobilized enzyme reaction rates could be performed in the DFBR. External and internal diffusional resistences usually play a significant role in fixed-bed reactors. However, for the experimental system studied, ...
On the basis of the equations derived previously [Tsou, C. L. (1965) Sheng Wu Hua Hsueh Yu Sheng Wu Wu Li Hsueh Pao 5, 398-408, 409-417] for the substrate reaction during the course of enzyme modification, the kinetic behavior of the system chymotrypsin-substrate-modifier has been studi...
3.1.化学反应速率RateofChemicalReaction化学反应速率是指在一定条件下反应物转化为生成物的速率，通常用单位时间内反应物浓度的减小或生成物浓度的增加来表示。1.瞬时速率 dc(P)limc/t t0 dc/dt dc(R)反应刚开始时，速率大，然后不断减小，故瞬时速率体现了反应速率变化的实际情况。
The thickness of the nylon layer was monitored by imaging analysis of the photographic data. More than 99 % of the copolymer with thicknesses of 260 nm (approximately 600 layers of polymer strands) were converted to water-soluble oligomers by nylon hydrolase (3 mg enzyme ml−1) at 30 °...
A new reaction of the crotonase superfamily. The enzyme 6-oxocamphor hydrolase, which catalyzes the desymmetrization of 6-oxocamphor to yield (2R,4S)-alpha-campholinic acid, has been purified with a f... G Grogan,GA Roberts,D Bougioukou,... - 《Journal of Biological Chemistry》 被引量...
By repeatedly adding substrate and bath reaction, the enzyme was used repeatedly, which greatly enhanced the utilization rate of enzyme (Scheme 1d). As started above, the emerging characteristics of the proteinosomes aggregations are superior to the individuals, and collective behaviors of “union ...
Measurement of enzyme activity in a Clinicon reaction rate analyser was carried out in two ways: one method was based on absolute calibration and the other used an enzyme standard which involved adjustment of results according to the value for the standard obtained in each batch. Batch calibration...
