而家 ， 我再將甘氨酸填上綠色 丙氨酸填紅色 絲氨酸 ， 即係大楷 S ， 填紫色 咁樣 ， 你能夠見到 上面嗰啲重複單位 差唔多都係綠色 、 紅色 同埋下面嘅重複單位好多都係紫色
Now, I'm going to fill in the glycine with green alanine and the red serine, which is the big block S, and fill in the purple so that you can see that the repeating units above are almost all green, red, and many of the repeating units below are purple
