铜虫 (小有名气)

[交流] 两句话的翻译!谢了。

The shift to a much higher mean particle size in the presence of chitosan and the disappearance of the native β-lg suggested that the β-lg was complexed by the chitosan。It should be noted that particle sizing was performed without prior centrifugation.However only 50% of the protein was sedimentable (insoluble) under these conditions (see Fig. 2) suggesting that simultaneous production of sedimentable and nonsedimentable (soluble) complexes was possible in some pH windows.
优秀是一种习惯!

原文:The shift to a much higher means particle size in the presence of chitosan and the disappearance of the native β-lg suggested that the β-lg was complexed by the chitosan。It should be noted that particle sizing was performed without prior centrifugation.However only 50% of the protein was sedimentable (insoluble) under these conditions (see Fig. 2) suggesting that simultaneous production of sedimentable and nonsedimentable (soluble) complexes was possible in some pH windows.
翻译:
位移值变得更高了说明粒子大小在壳聚糖表面已经显现,同时找不到乳球蛋白的信号,这就表明乳球蛋白已经和壳聚糖形成了聚合物复合体。应该注意的是在粒子形成之前不要离心,在这些条件下(见图2),尽管只有50%的蛋白质可溶,但这至少说明了在某种PH值条件下不溶性和可溶性复合物是可以同时生成的。
做不做是态度问题,做得好不好是能力问题,前者关系着做人,后者关系着做事!

我的理解不同:

由于壳聚糖的存在以及天然β-lg的缺失导致平均粒径值增大,这表明β-lg 已被壳聚糖
络合。注意在粒子形成之前勿需事先离心。然而,在图2所示条件下(如图),仅有50%的蛋白质可以沉淀析出(不溶性),这也意味着在某个PH值点上,可同时生成可沉淀及不可沉淀(可溶性)络合物。
