The micronutrients, the vitamins part of the micro nutrients,微量元素 微量元素之一的维生素 -
would fall into several categories.各自属于不同的分类 -
They're water soluble and fat soluble vitamins分为脂溶性维生素和水溶性维生素 -
that look like this,像这样 -
and the difference between the two is二者的区别在于 -

There can be a supply of them,从而在体内建立起一个供应源 -
a storehouse of them that can build up in the body,一个脂溶性维生素仓库 -
and so day-to-day fluctuations become less of a problem这样一来 相比起水溶性维生素 -
with fat soluble then water soluble vitamins,脂溶性维生素的浓度不会每天剧烈波动
