Voltammetric determination of ascorbic acid in the presence of acetaminophen and tryptophan using an improved carbon nanotube paste electrode(图)
Ascorbic acid Acetaminophen Tryptophan Carbon nanotube paste electrode Electrocatalysis
2013/9/26
A carbon paste electrode (CPE) modified with carbon nanotubes and 5-amino-3',4'-dimethyl- biphenyl-2-ol (5ADB) is prepared. Under the optimum pH of 7.0, the oxidation of ascorbic acid (AA) on the modi...
Spectrophotometric Method for Determination of Tryptophan in Protein Hydrolysates
protein hydrolysates tryptophan spectrophotometry diphenylamine
2009/2/26
A novel spectrophotometric method for determination of tryptophan content in protein hydrolysates has been developed. The reagent used is diphenylamine sulphonate which is oxidised to diphenylbenzidin...
以酶法合成γ-D-glutamyl-L-tryptophan (γ-D-Glu-L-Trp)为研究体系,采用D-谷氨酰胺为γ-谷氨酰基供体,L-色氨酸为受体,测定得到了转肽反应的米氏常数(K m)为5.11 mmol·L-1,催化常数(Kcat)为3.92 mmol·min-1,γ-D-Glu-L-Trp的水解反应米氏常数(K′m)为2.31 mmol·L-1,催化常数(K′cat)为1...
Nonproteic Contents Interfere with the Analysis of Added Tryptophan in Feeds � Test of a Correction Model
Free nonproteic Tryptophan amino acid analysis supplementation
2009/1/14
The nonproteic, free tryptophan contents in 23 important feed ingredients were analysed. Wheat, its bran and middlings, soybean meal, sunflower meal and other vegetable feed ingredients contain signif...
Site-Directed Mutagenesis of Tryptophan 622 of Thermoactinomyces vulgaris R-47 Glucoamylase:pH Optima and Activities of Five Mutants
glucoamylase optimal pH catalytic base
2008/4/20
In Aspergillus awamori glucoamylase, the optimal pH has been reported to increase to maintain activity by a mutation of Ser411 which forms a hydrogen-bond with a catalytic base (Fang and Ford, Protein...
Tryptophan Catabolism by Lactobacillus caseiand Lactobacillus helveticus Cheese Flavor Adjuncts
Lactobacillus amino acid catabolism tryptophan cheese flavor
2008/3/31
Microbial degradation of Trp is thought to promote the formation of aromatic compounds that impart putrid, fecal, or unclean flavors in cheese, but pathways for their production have not been establis...
