This early prebiotic history has been lost from the terrestrial record. 这种早期前生命历史已经从地球记录里消失。
This has led many to argue that the starting point for the history of life on Earth was the denovo emergence of the RNA world from a nucleotide-rich prebiotic soup. 这使得很多人主张,地球生命历史的起点是在富含核酸的汤里反复出现的&也就是RNA世界。另外一些人非常怀疑这一观点。
One of the things we're trying to look at is prebiotic seif-organisation, chemical seif-organisation. 我们要考察的内容之一是生命起源前的自组织,化学自组织。
The origin of life is a hotly debated topic, and the source of the prebiotic chemicals in Earth's so-called primordial soup is one of its enduring mysteries. 生命的起源是一个热议中的话题。其中一个由来已久的谜团是:在地球上所谓的“原始汤”中,生物前化学物质究竟来自何处呢?
Electric Discharge of the Gas Mixtures of HCN, H2S, PH3, N2-NH3 and CH4-H2O& Simulating Prebiotic Synthesis HCN、H2S、PH3、N2-NH3与CH4-H2O气体混合物的前生物分子合成
Objective To investigate the prebiotic effects of fructo oligosaccharide ( FOS) in an enteral formula for children with malignant tumors. 目的评价肠内营养低聚果糖(FOS)配方在恶性肿瘤患儿中的应用价值和前生物效应。

Potential role of h_2 CN radicals in prebiotic synthesis H2CN自由基异构体在前生物分子合成中的可能作用
A range of health benefits were demonstrated with resistant starch, including improvement on bowel health, prebiotic, regulating blood glucose and insulin response and increasing mineral absorption. 抗性淀粉有很多健康功能被阐述和报道,包括改善肠道健康,益生源,调节血糖和胰岛素反应,促进矿物质吸收等。
The Method of Analyses of Nucleic acid Bases for Prebiotic Synthesis Studies 应用于预生物合成研究的核酸碱基分析方法
It is of signification to study further the prebiotic synthesis of polypeptides, the biosynthesis of proteins and application in the synthesis of polypeptides using organic phosphorus as the activating reagents of amino acids. 因此,利用有机磷作为氨基酸的活化试剂,不仅对于揭示多肽的前生物合成和蛋白质的生物合成具有重要理论意义,而且对于多肽的合成也具有应用价值。
Phosphorus plays an important role in prebiotic evolution and in process of the life, which is known as "the control center of the life activities". 磷在生命活动过程中起了非常重要的作用,参与了生命体系中大多数的生物化学过程,因此被人们誉为生命活动的调控中心。
Objective GOS is a prebiotic, it has many research about the impact of prebiotics on the intestinal mucosal barrier and the gut microflora mechanism. It has achieved good results in animal experiments. 目的低聚半乳糖是一种益生元,国内外目前对益生元对肠粘膜屏障及肠道微生态的影响机制有较多研究,且动物实验中已经取得了良好的效果。
Bifidobacterium was a kind of important dominant prebiotic in intestinal of healthy people, providing a series of physiological functions such as improving intestinal microflora, regulating immune ability, smoothing intestine and defecating feces excretion. 双歧杆菌是健康人肠道内定植数量占优势的一种重要的益生菌,具有润肠通便、改善肠道微生态菌群、免疫调节等一系列的生理保健功能。
