摘　　要：主要阐述了废弃鸡蛋壳的化学组成以及其中生物活性物质唾液酸的生物学功能问题。废弃蛋壳包括蛋壳、蛋壳膜和残留蛋清,含有唾液酸、糖醛酸以及氨基酸等成分。其中唾液酸是一类分布在复合糖类糖链末端的九碳糖,在各种生命活动中起着重要的作用,如体内润滑、维持正常神经活动、益智、抗菌、抗病毒、抗肿瘤等,旨在为废弃蛋壳中唾液酸的开发利用以及今后相应的科研工作提供理论依据。Chemical composition of wasted eggshell and biological functions of sialic acid in eggshell were reported.Wasted eggshell consists of eggshell, eggshell membrane and rudimental egg white, with sialic acid, uronic acid and amino acid.Sialic acid is a nine-carbon monosaccharide found on the terminal of glycoconjugates. It plays an important role in life activities and internal lubrication, maintain normal activity of nerves, alpiniae oxyphyllae,antibiosis,virus resistance,anticancer.The study will afford rationale for development and utilization of sialic acid in wasted eggshell.
