hydrophilic groups 中文意思是什麼

hydrophilic groups 解釋
（親水基團）：與水結合從而蛋白質的親水區域或脂質雙分子層處於水環境中。

  1. Molecules with both hydrophilic and hydrophobic groups are called amphipathic or amphiphilic.

    分子兼有親水的和疏水的兩個基團，叫做兩性的或兩親的。
  2. 2. there were statistically differences between the groups in acidity and compressive strength changing at the first 6 weeks after degradation test, mass loss and intrinsic viscosity changed significantly in whole period, volume contract happened after the 2nd week ( p < 0. 05 ). 3. after modified with alginate calcium, the scaffolds have the much higher hydrophilic ability, water uptake reached 50 - 60 % ( v / v ) from 0. 5 to 24 hours, no significant difference found between the inner groups

    經過藻酸鈣改性后的支架親水性能得到良好改善，體積含水量在24小時內保持在5o朋之間，區組、組內比較無顯著性差異中勸刀5 ） ；酒精處理后吸水率達到個12之間，顯著高於對照組的2 10 ，區組和組內比較均存在顯著性差異（卜
  3. And some methods for improving their poor solubility are introduced, including : incorporating bulky groups, hydrophilic groups, water soluble polymers and hyper - branched dendrimers ; synthesizing branched derivatives ; and degrading them into oligosaccharide

    對其解決的方法進行了分析總結：將體積較大的側基或親水性基團大分子引入到分子鏈上，支鏈化或鍵接超支化合物，以及低聚糖化，以滿足不同應用領域特別是生物醫學工程的要求。
  4. These 20 amino acids fall into different groups based on their chemical properties : acidic or alkaline, hydrophilic ( water - loving ) or hydrophobic ( greasy )

    這20多種氨基酸依據屬性不同可分成不同的類別：酸性或是堿性，親水或是親油。
  5. Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process

    將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中，獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合，在分散體粒子內產生擴鏈交聯反應，生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明，此分散體具有極大的工業應用價值
