摘要
乳中不但含有营养成分,还含有多种生物活性物质。糖蛋白作为乳中具有生物活性的多糖复合物,能够起到防止病原菌感染、调节肠道微生物菌群和免疫防御等作用。本文综述了蛋白质糖基化的类型、研究方法、乳中主要糖蛋白的组成、糖基化位点、糖链结构及乳糖蛋白的生物学功能的研究进展,旨在为进一步研究乳蛋白质糖基化提供参考,为利用乳中具有重要生物学功能的糖蛋白提供一定的理论依据。
Milk is not only rich in various nutrients,but also contains iboactive substances which have been documented to exert protective effects in the human body.Milk glycoprotenis play a role in protecting against pathogen infection,modulating the intestinal flora and regulating the immune systme.This paper summarizes the types of protein glycosylatio n and the methods used to study protein glycosylation and review smilk glycoprotein composition,glycosylation sites,glycan structure and bioactive functions of milk glycoproteins,aiming at providing useful information for further study an d utilization of these important bioactive glycoproteins.
