英語翻譯
蛋白質的胺基酸分子中既含有氨基,又含有羧基,是一種兩性物質.當外界溶液的pH 與蛋白質的等電點不同時,蛋白質會帶有不同的電荷,從而對帶有相反電荷的物質產生吸附作用.
蛋白質與單體的吸附等設計出了一種合成單分子蛋白質納米微囊的方法.該方法分成兩步.半胱氨酸蛋白酶-3(CP3) 的表面修飾:以靜電力、范德華力等物理吸附方式將單體( 丙烯醯胺,N-(3-丙氨基) 甲基丙烯醯胺) 連接於蛋白質表面;( b) 採用雙丙烯醯化Val-Asp-Glu-
Val-Asp-Thr-Lys(CL-VDEDTK) 爲交聯劑,在溶液中進行原位自由基聚合反應形成聚合物包埋層.

解答：

Protein molecules of amino acids contain both amino and containing the carboxyl group, is a gender material. When the pH of the solution from the outside does not coincide with the isoelectric point of the protein, protein with different charge and adsorption of substances of opposite charge.
Adsorption of protein monomers devised a method of synthesis of proteins in a single molecule Nano-microcapsule. The method is divided into two steps. Cysteine protease -3 (CP3) of surface modification: physical adsorption methods, such as static electricity, van der Waals force monomer (Acrylamide, n-(3-amino) methyl acrylamide) attached to the protein surface, (b) use two-acrylamide Val-Asp-Glu-
Val-Asp-Thr-Lys (CL-VDEDTK) as cross-linking agents, in-situ radical polymerization reactions forming polymers in solution embedding layer.
