12、st positi ons 课题 2 探讨加酶洗衣粉的洗涤效果 当你自己动手洗衣服的时侯，会发觉有油渍、汗渍或血渍的衣服很难彻底洗干净，你是 如何解决这个问题的？在本课题中，我们将了解加酶洗衣粉的作用，探讨加酶洗衣粉运用的最适条件。新课1基础学问 活动 1 ：阅读课题背景及基础学问，探讨并完成学案 1 1 加酶洗衣粉是指含有酶制剂的洗衣粉 ,目前常用的酶制剂有四类：蛋白酶 、 脂 肪酶、淀粉酶 、 纤维素酶 。其中应用最广泛、效果最明显的是 碱性蛋白酶 和 碱性脂肪酶 。思索 1碱性蛋白酶为什么具有如此强的功效？它的作用机理是怎样的？请写出作用示意图。酶具有高效性， 能快速将血渍、 奶渍等含有

13、的大分子蛋白质分解成可溶性小分子肽和氨基酸。蛋白质 蛋白酶 多肽 肽酶 氨基酸思索 2你能写出脂肪酶、淀粉酶和纤维素酶的作用示意图吗？ 脂肪酶 脂肪甘油脂肪酸 淀粉酶 淀粉麦芽糖 纤维素 C 1 酶、 Cx 酶 纤维二糖 葡萄糖苷酶 氨基酸 1. 2影响酶活性的因素有 温度 、 酸碱度 和 表面活性剂 。思索 3酶能干脆添加到洗衣粉中吗？为什么？科学家是如何解决这一难题的？不能，因为洗衣粉中的表面活性物质会降低酶的活性。将基因工程生产出的酶用特别水溶性物质包袱起来，与洗衣粉的其它成分隔离开来。思索 4为什么说加酶洗衣粉能削减对环境的污染？ 加酶洗衣粉可以降低表面活性剂和三聚磷酸钠的用量，使洗涤

14、剂朝低磷、无磷的方向发展。一般洗衣粉的化学成分有：表面活性剂、水软化剂、碱剂、漂白粉等成分，有的洗衣粉中还含有增白剂、香精和色素，以及填充剂等。2. 试验设计 To sum up, is divide d int o 9 main part s: 1. wit h regard t o persi sting a nd developing soci alism with Chi nese chara cteristi cs. 18 since the XIOn mor e than one occasi on, General Se cretary of the hist orical or
