中文摘要：

糖胺聚糖（GAGs）是鸡蛋壳有机组分中的重要组成部分,参与形成蛋壳的超微结构,进而调控蛋壳品质,其分泌贯穿蛋壳形成的全过程。本文从GAGs的种类和生物活性、在蛋壳中的分布和对蛋壳超微结构的作用,及蛋壳中GAGs的调控等方面,简述了GAGs影响蛋壳品质的研究进展,以期为蛋壳品质的研究提供新思路。

英文摘要：

Glycosaminoglycans（ GAGs） are one of the important constitute of eggshell organic matrix,which is involved in the formation of eggshell ultrastructure,and consequently affects eggshell quality. GAGs are synthesized and secreted in the process of eggshell formation. In the paper the GAGs families and their bioactivities,distributions and effects of GAGs on eggshell ultrastructure,and modulation of GAGs in eggshell were presented,meanwhile,research progress on the effects of GAGs on regulation of eggshell quality was reviewed with the aim of providing a newidea for eggshell quality improvement.
