Qiangli′an brand sterilant (stable ClO2) is colorless, tasteless, nonpoisonous, non－corrodent and transparent liquid, being a strong oxidant, it can resolve and oxidize the amino acid of microbial protein, break the amino acid chain and lead to microbial death.

摘 要：强力安灭菌剂是无色、无味、无毒、无腐蚀的透明液体，是一种强氧化剂。可使微生物蛋白质中的氨基酸氧化分解，导致氨基酸链断裂，蛋白质失活，使微生物死亡。

In this study, they constructed a ground squirrel protein database using computational methods. They further analyzed the protein expression in hibernating ground squirrels using high-throughput label-free LC-MS/MS.

And adsorption of jack bean proteins onto the amphoteric resin was studied in this paper. The amphoteric resin was in innersalt form. The results of adsorption experiments show that when the proteins are adsorpted into the amphoteric resin in the neutral phosphate buffer solution, the diffusion coefficient of protein is near twofold in 0.4 mol/L NaCl phosphate buffer solution than that in solution without salt, and the adsorption capacity of protein also rises at the same ti...

通过盐浓度对吸附的动力学和热力学影响的研究，结果表明，在中性磷酸盐缓冲液中，两性树脂吸附刀豆蛋白，有盐( 0 。4mol/L Na Cl)的比无盐的扩散系数提高将近一半，且吸附量增加，其吸附等温线的效率在最初始部分高于无 Na Cl时的；随着盐浓度( 0～ 1 mol/L Na Cl)的提高，树脂对蛋白的吸附量也变大，盐浓度提高时树脂膨胀体积的增大与蛋白吸附量的增加呈线性关系，内盐型两性树脂对大分子蛋白质的吸附作用与小分子高价离子的相似，同样是通过内盐键破裂吸附。

I have been macrobiotic, vegetarian, vegan, no fat, all fat, no protein, and high protein.

我觉得控制食物似乎是最好的方法，于是我几乎尝试了每一种食疗方法：长寿主义、素食主义、无脂肪、全脂肪、无蛋白质和高蛋白质等食谱。

A sterile liquid containing proteins extracted from cultures of tubercle bacilli and used in tests for tuberculosis.

结核菌素从结核培养菌中提取含有蛋白质的无菌液体，用于肺结核测试

In this study, we discussed the phylogenetic relationships in the Anura groups with the sequences of the 12 proteins encoded in the H-strand and 22 tRNAs of mtDNA from 21 species from GenBank. They all indicated that Anura were divided into the Archaeobatrachia and the Neobatrachia,these results supported the monophyletic origin of Anura.

结合饰纹姬蛙和金线蛙的mtDNA以及GenBank上公布的共21种无尾目的线粒体基因组，本文基于编码重链12个蛋白质的基因和编码22个tRNA的基因分别构建了MP系统树，分析了21种无尾目动物的亲缘关系，结果都显示将无尾目分为两大群，支持无尾目的单系起源。

Seeds couldnot maintain the ability of synthesizing proteinwhen they lost viability.High vigor seedsbegan protein synthesis after imbibition wasstarted and kept a higher rate than low vigorseeds in the whole process of imbibition.

无活力种子已丧失合成蛋白质的能力，高活力种子吸胀开始即进行蛋白质合成，且整个吸胀过程中合成蛋白质速率较低活力种子高。
