一正如用十二个音律可以作出无数回肠荡气的交响乐,二十六个拉丁字母便可构成无数单词,组成丰富的语言,蛋白质是由二十个“氨基酸”通过不同种类的排列而组成的。目前已发现了成千上万种之多的蛋白质。蛋白质中最小的一种叫做“胰岛素”。这古怪的名词儿!它是我们每个人的躯体里面都有的。在人和动物的腹腔之内,小肠旁边,都有一个胰脏。早先,科学家从这胰脏的切片中,通过显微镜,观察到一种孤岛似的细胞群,分泌出一种荷尔蒙,即激素:这种胰脏中的胰岛细胞分泌的激 Just as the twelve rhythms make a myriad of symphonic vocals, twenty-six Latin alphabets form countless words and make up rich language.
