It was observed that the catalytic activity of PVA matrix increases with the crosslinking degree, due to the increases of the amount of sulfonic acid groups on PVA. Further, the influence of various reaction parameters, such as, catalyst loading, initial concentration of sucrose and temperature, ...
Enzymatic hydrolysisis rarely used except for the determination of glutamine andasparagine, which are converted to aspartic andglutamic acidstogether with ammonia byacid hydrolysis. Since no singleproteasewill hydrolyze all thepeptide bondsin proteins, the procedure is lengthy, and there is evidence of ...
10. Explain why an equimolar mixture of D- glucose and D-fructose formed by hydrolysis of sucrose is called invert sugar in the food industry. 解释为什么蔗糖水解产生的D-葡萄糖和D-果糖等摩尔的混合物在食品工业上称为转化糖? 11. hydrolysis的反义词 ...
Succinic acid (SA) is an intermediate product of the tricarboxylic acid cycle (TCA) and is one of the most significant platform chemicals for the production of various derivatives with high added value. Due to the depletion of fossil raw materials and the demand for eco-friendly energy sources...
The rate constant is the same compared to diluted homogenous acid solution. Hydrophobic interactions essentially contribute to the adsorption of the sucrose molecule but not to the energy of the activated transition state. It was proved that the zeolite pores are able to include a sucrose molecule ...
The production of reducing sugar was determined using the 3.5-dinitrosalicylate reagent where sucrose and cellulose were used as substrates (Miller, 1959). One unit of enzyme activity (U) was defined as the amount of enzyme that releases 1.0 μmol of product per min under the assay conditions...
The possible hydrolysis of sucrose to reducing sugars during processing also is to be considered . 当然也要考虑加工过程中蔗糖有可能水解变成还原糖。 Acid-hydrolysis and hydrolysate decolorized conditions for compound amino-acids production from duck feather are studied by using orthogonal tests. 通过正交...
Hydrolysis of a sugar has its own name: saccharification. For example, the sugar sucrose may undergo hydrolysis to break into its component sugars: glucose and fructose. Acid-Base Acid-base catalyzed hydrolysis is another type of hydrolysis reaction. An example is the hydrolysis of amides. ...
The ground scales were subjected to an acid hydrolysis using 6 N HCl and 0.1 % phenol. Hydrolysis was carried out at 110 °C for 24 h. The derivatization of the samples was done before the pre-column, using o-phthalaldehyde (OPA) for primary AA and 9-fluorenyl methyl chloroformate...
