The detected tryptophan-like fluorescent components are mainly protein-like substances, which may be derived from the human activities such as human excreta, food residues and cooking oils [44]. Based on Fig. 2b, the averaged fluorescent peak intensity of tryptophan-like T1 and tryptophan-like T2...
Tryptophan and tryptophan-like substances were quantified in cloud water sampled at the puy de Dme station.The fate of tryptophan was investigated in the cloud aqueous phase under sun-simulated conditions.The hydroxyl radical-mediated transformation of tryptophan in cloud water can be considered to be...
Determination of tryptophan and indole substances by a colorimetric diazotisation method 来自 掌桥科研 喜欢 0 阅读量: 47 作者: AK Goswami 摘要: A colorimetric method for the determination of tryptophan in protein hydrolysates by its conversion into nitrosamine with nitrous acid followed by diazo...
Tryptophanis an essential amino acid that is mainly derived from dietary protein metabolism (Zhang and Davies, 2016). Once metabolized, tryptophan is released into the blood stream or absorbed by the intestines to be used for physiological processes, like protein-, serotonin-, and melatonin synthesi...
The inhibitor shows some protein-like properties and acid hydrolysates were found to contain substances sensitive to ninhydrin. However, the hydrolysates also contain substances, presumably sugars, sensitive to benzidine reagent, appreciable sugar in galactose equivalents, and some fluorescent substances. ...
3DEEM revealed that the variation of DON in the coagulation and adsorption tests depended intimately on tryptophan protein-like substances, aromatic protein-... LIU Bing,YU Guozhong,GU Li,... - 《环境科学》 被引量: 10发表: 2013年 加载更多来源...
However, the substances involved in the first event during postembryonic germ cell development, i.e., ovarian development, remain unknown. Here, we aimed to identify a bioactive compound associated with postembryonic ovarian development. Bioassay-guided fractionation identified l-tryptophan (Trp) on ...
In the body can be converted into 5 serotonin, nicotinic acid, melanin Nervousness, pineal hormone and yellow uric acid and other physiological active substances. When the human body lacks tryptophan, it will not only cause general hypoproteinemia, but also produce skin diseases, cataracts, ...
Maize also contains a tryptophan synthaseα-like protein, unlinked to a tryptophan synthase β protein, that produces free indole [23]. Thus, there exists the potential for fine-tuning the regulation of this pathway by differential regulation of the expression of these genes, or differential ...
