There were 5 . 9 tip residues in cml . the purified cml was modified with n - bromosuccinimide ( nbs ) in hac - naac buffer containing 8mol / l urea or not 在含8mol l脲和不含脲的缓冲体系中,用n -溴代丁二酰亚胺( nbs )修饰cml的色氨酸残基。
Researchers recently discovered that a nutrient called tryptophan , present in figs , may make this fruit the perfect late - night snack to promote sound sleep 研究员近日发现在无花果里有一种称为色氨酸的营养成分,可使其成为最佳宵夜也有助于睡眠。
Aromatic metabolites such as tryptophan , phenylalanine , tyrosine which can only be synthesized by plants and microbes are essential amino acids for human and animals 芳香族氨基酸包括酪氨酸、苯丙氨酸和色氨酸,是人体和动物体内的必需氨基酸。
The experiments suggested that trp , tyr , asp or prote in containing these amino acids in human body may promote the formation of urinary stone 上述实验表明人体中的色氨酸、酪氨酸,特别是天冬氨酸或者是包含有这些氨基酸的蛋白质可以促进尿结石的生成。
The protein hydrolytic amino acid content is 11 . 65 % , among them , glu content is the highest , about 1 . 75 % , and the phe content is the lowest about 0 . 03 % 结果表明,在常见的18种氨基酸中,除了色氨酸在酸性环境下遭到破坏,其余的17种氨基酸都存在检侧图谱中。
The adsorption behaviours of tryptophane on graphite hopg have been investigated under low vacuum conditions at room temperature using scanning tunneling microscopy 用扫描隧道显微镜stm研究了室温下色氨酸分子l - tryptophane在石墨hopg表面的吸附行为。
Serum levels of 5 - ht and tryptophan were significantly lower in patients with depression who had a recent suicide attempt than in those patients who had never attempted suicide 血清5 -羟色胺与色氨酸浓度,最近有自杀意图病人比从未有自杀意图病人显著偏低。
Mutant gene affected m - centrin propertities . from uv different spectrum , we know that there are fine absorption of tyr and trp apart from those of phe 实验表明:从紫外吸收图谱看,突变之后的中心蛋白中除了苯丙氨酸的精细结构外还有酪氨酸和色氨酸的吸收峰。
Using ki , cscl and acr to probe the micro - environments of trp residues in dpl , the trp residue fluorescence of dpl was not quenched by ki and cscl , but 100 % quenched by acr 在含脲的体系中可修饰36个色氨酸残基;在不含脲的缓冲体系中可修饰12个色氨酸残基。
Baseline levels of tryptophan were measured on that day and patients completed a questionnaire , answering questions about ibs symptoms and symptoms of anxiety and depression 之后测量色氨酸的基线水平,并让患者完成一份问卷调查,回答一些关于ibs的症状和焦虑抑郁症状的问题。
