生物活性
α-Lactose 是牛奶中的主要糖。Lactose 以 α 和 β 两个异构体的形式存在。α 形式通常以一水合物的形式结晶。体外研究
Lactose is a very important sugar because of its abundance in the milk of humans and domestic animals. Lactose is a valuable asset as a basic nutrient and the main substrate in fermentative processes that led to the production of fermented milk products, such as yogurt and kefir.
