90年前,英国化学家霍普金斯在使用人工合成饲料喂养动物的过程中发现了维生素。从此,他解开了因缺少这一微量物质而引起的特异疾病之谜,并为这些病的治疗找到了一条正确途径。存他之后,科学家们发现了二十多种维生素,并开创了一条人工合成维生素之路。维生素,又称维他命(VITAMIN),顾名思义,是维持生命不可缺少的物质。人和动物缺了它就不能正常生长,并会发生特异性病变——维生素缺乏症。
Ninety years ago, British chemist Hopkins found vitamins in animals fed artificial feeds. Since then, he has solved the mystery of specific diseases caused by the lack of trace substances and found the right way for the treatment of these diseases. After saving him, scientists found more than 20 kinds of vitamins, and created a road of synthetic vitamins. Vitamins, also known as vitamins (VITAMIN), as the name suggests, is an indispensable substance to sustain life. People and animals can not grow normally without it, and there are specific lesions - vitamin deficiency.
