The basic research of primary lactase deficiency / 国际儿科学杂志

ABSTRACT

Lactose is one of the important nutrients in milk.It is decomposed by the lactase enzyme and plays an important role in the life activities of cells in human health.Due to the lack of lactase,the symptoms of lactose intolerance occur highly in Chinese population,thus limiting the large part of the people to drink milk.Milk is a good source of high-quality protein,minerals and vitamins for the human,so the problem of lactase deficiency also seems particularly severe.
