The hair ' s main composition is an amino acids , amino acids to can suffer the outside to affect in the factor and run off , and also can is influence by the internal factors with the chemicals ' s damage such as the weather season , if the body mainutrition , hair lack the vitality with the flexibility , therefore want to with regularity add the amino acids , it the contain to permeate the differential calculus son to can quickly permeate the hair the consolidation repair and maintenance for , becoming bing arrived by outside inside of deep place the amino acids composition , and make the hair shining brilliance , movement contain flexibility every moment 头发的主要成份是氨基酸，氨基酸会受外有因素影响而流失，如气候季节和化学品的损害，也会受内在因素的影响，如身体营养不良，头发缺乏活力和弹性，所以要定期地补充氨基酸，本品特含渗透微分子能迅速将氨基酸成份渗透头发深处，形成由外到内的巩固修护，使头发时刻焕发光彩，动感有弹性。
So in this paper , effects of dietary protein levels on the content of protein and amino acid profile in hepatopancreas and ovaries during ovarian maturation are investigated on basis of analyzing protein content and amino acid composition and content in hepatopancreas and ovary of broodstock in nature . influence of dietary protein on concentration of lipovitellin in ovary of broodstock after purification and preparation antibody of lipovitellin from mature ovaries of e . sinensis is evaluated . and nutritional requirement for arginine and lysine , and interaction between protein and vitamin b6 of juvenile e . sinensis are also studied 华东师范大学2003届博卜学位论文为此，本研究在弄清中华绒鳌蟹自然条件下卵巢发育过程中肝胰腺和卵巢的蛋白质含量及其氨基酸组成的基础上，探讨了饵料蛋白质水平对其卵巢发育过程中肝胰腺和卵巢的蛋白质含量及氨基酸组成的影响;在制备中华绒鳌蟹成熟卵巢卵黄磷蛋白抗体的前提下，研究了蛋白质营养对成熟期卵巢卵黄磷蛋白合成的影响:并对仔蟹期的部分必需氨基酸适宜需要量，蛋白质和维生素b6的相互作用进行了研究。
In this paper , the nacre of hyriopsis cumingii ( lea ) which is one of the main freshwater pearl - forming mollusk in china is studied emphatically , as compared with the nacre of three species of saltwater pearl - forming mollusks , pinctada martensii ( dunker ) , pinctada maxima ( jameson , and peteria penguin ( roding ) . the basic characteristics of nacreous and prismatic layers are understood by powder x - ray diffraction analysis , trace elements analysis , amino acid composition of protein and differential thermal analysis 本文以我国主要育珠蚌淡水三角帆蚌贝壳珍珠层为重点研究对象，以三种海水育珠贝马氏珍珠贝、企鹅珍珠贝及大珠母贝贝壳珍珠层为对比研究对象，首先通过粉末x -射线衍射、微量元素分析、蛋白质氨基酸分析及差热分析对珍珠层及其与之密切共生的棱柱层的基本特征进行了初步研究。
The results indicated that broom flower is 50 % , 80 % and 100 % higher in protein , fat and carbohydrate content respectively than the ten vegetables , and the amino acid composition is balanced and the content reaches 1875 . 55mg / 100g , with 37 . 92 % of essential amino acids . the trace element zinc and selenium , and vitamin b2 is significantly higher than the ten common vegetables 结果表明，金雀花的蛋白质、脂肪和碳水化合物的含量比10种常见蔬菜平均值分别高5溅， 8既和100 % ;氨基酸种类齐全，含量达1875 . 55mg / 1009 ，人体必需氨基酸占氨基酸总量的37 . 92 % ;微量元素锌和硒，维生素b2等营养成分，明显高于10种常见蔬菜。
There were little difference in the amino acid composition of antigen domain of a , b and c between c strain from rabbit spleen tissue and virulent strains above . this indicated that the prevalence of csf and immunal failure may be not caused by the antigen variation of c stain vaccine virus . the e2 genes of 51 csfv prevalent virulent strains isolated from 12 provinces in china were amplified and sequencd 对c -株兔脾毒与c -株细胞毒、经典强毒e2上的a 、 b 、 c三个中和性抗原区的氨基酸组成进行了比较，其结果为： c -株兔脾毒与c -株疫苗细胞毒的差异很小甚至没有差异。
The hwtx - i gene was chemically synthesized according to its known cdna sequence , the gene was inserted into vector ppic9k which contained aoxj promotor and the sequence of a secreting signal peptide - a - factor , the cloning ppic9k / hwtx - i was constructed and confirmed by two - step pcr and dna sequence analysis , then it was transformed into host strain gs115 , a his + muts cell line was screened and multicopy transformants were screened by various g418 concentrations , the multicopy transformant was named gh1 . gh1 was cultivated in flasks . after 6 days of induction by 0 . 5 % methanol , the supernatant was checked by 16 . 5 % tricine - sds page , which showed there was a band in the position of 3 . 5 - 6 . 1kd , then it was isolated and desalted by ultrofiltration followed by ion exchange of cm column , after reverse phase hplc of ci8 and vacuum drying , the purified rhwtx - 1 was obtained which was proved to be correct recombinant hwtx - i by tricine sds - page , maldi - tof mass spectrometry , amino acid composition analysis , the n - terminal amino acid sequence and its biological activity , the final field of the purified rhwtx - i was about 80mg / l , accounting for 23 . 6 % of it total secretory proteins 将带有hwtx -基因的ppic9k经blgii线性化后，转化酵母宿主菌gs115原生质体后经筛选阳性克隆并经表型鉴定为his ~ + mut ~ s酵母菌，进一步用遗传毒素g418筛选多拷贝的转化菌株，命名为gh1 ；将gh1甲醇酵母菌用0 . 5的甲醇诱导表达，发酵上清经90饱和度的( nh _ 4 ) _ 2so _ 4沉淀， yw - 3 ( mwc03000 )的超滤膜超滤，再经cm阳离子交换， c _ ( 18 )反相hplc纯化得到分子量为4kd左右的组分，其中4289 . 05的组分经质谱鉴定，氨基酸组成分析和序列测定为正确的表达产物，生物学活性表明其活性为天然毒素活性70 % ，表达量为80mg / l 。
Was released , which was confirmed by molecular mass and amino acid composition analysis . ultraviolet and circular dichroism spectra were used to test the secondary structure of - mt - 3 . distinct from other - mt , - mt - 3 showed a negative trough at about 220nm in the cd spectrum , suggesting that an - helix might exist in its secondary structure 紫外吸收光谱及圆二色性光谱研究重组- mt - 3的结构。 mt - 3的与其余mt的结构域不同， - mt - 3的圆二色性光谱在220nm左右为负峰，说明- mt - 3可能包含一个-螺旋的二级结构。
Whey protein is biological active protein extracted from milk with high biological utilization value rich of immunoglobulin , lactoferrin , cgmp and other active eelements , and whey protein is famed as “ king of protein ” for the high purity and absorption rate and best amino acid composition 乳清蛋白是从牛奶中提取出来的生物活性蛋白，具有很高的生物利用效率，富含免疫球蛋白、乳铁蛋白、糖巨肽等多种活性成分，以其纯度高、吸收率高、氨基酸组成最合理等诸多优势被推为“蛋白之王” 。
