鲍壳形态结构及蛋白质组分研究

Morphological Structure and Protein Components of Abalone Shells

[目的]研究鲍壳的形态结构、蛋白质含量及组分。[方法]采用扫描电镜观察鲍壳横断面的形态结构,采用凯式定氮法测定鲍壳的蛋白质含量,采用离子色谱仪技术分析蛋白质水解后的氨基酸组分。[结果]电镜下观察鲍壳横断面为交叉层状结构,片层之间有蛋白质相连接,鲍壳蛋白质含量高达22%。氨基酸分析表明,鲍壳中含有人体必需的多种氨基酸组分。[结论]试验验证了鲍壳的微观结构,探讨了其蛋白质含量及氨基酸组分,鲍壳的药理学作用可能与鲍壳的蛋白质含量有关。

[ Objective ] To study morphological structure and protein components of abalone shells. [ Method ] Using scanning electron micro- scope to observe morphological structure of cross section of abalone shells, Kjeldahl N determination method to get protein contents of abalone shells, ion chromatograph to analyze amino acid component after protein hydrolysis. [ Result] The cross section of abalone shells shows crossed hierarchies, proteins connect the hierarchies, and the shell protein content achieves 22% and above, amino acid analysis shows that human body contains many amino acid components. [ Conclusion] Microscopic structure of abalone shells is proved, protein content and amino acid components are explored, pharmacological action of abalone shells mac be related to its proteins.
