人体能生长发育,端赖空气和食物的不断供给。空气和食物到了人体里面之后,就发生同化和异化的作用,结果,人体不但能生活,而且能生长发育了。这种同化和异化作用,实际上都是很复杂的化学作用;由于这种作用的结果,造成了酸类、硷类和盐类(或酯类)的许多化合物,不论是无机的或有机的都有,所以人体就是一个最复杂的化工厂。这个化工厂的几种出品,世界上第一等的天才化学工程师,至今还不能用人工仿造,这是多么神秘呀!
The human body can grow, depends on the constant supply of air and food. After air and food reach the human body, assimilation and alienation occur. As a result, the human body can not only live but also grow and develop. This assimilation and alienation are in fact very complex chemistries; as a result of this action many compounds of acids, bases and salts (or esters) are produced, whether inorganic or organic There are, so the human body is one of the most complex chemical plant. This chemical plant produced several, the world’s first genius chemical engineers, still can not use artificial imitation, it is so mysterious!
