以天然高分子壳聚寡糖为原料,通过在壳聚糖2位-NH2上引入部分疏水性烷基,在6位-OH上引入亲水性羟乙基,制得N-十二烷基-O,N-羟乙基壳聚糖(LGC)两亲性衍生物,分别用FTIR、1HNMR和元素分析等技术对其结构进行表征.此壳聚糖衍生物在水相中自组装形成胶束,以芘为荧光探针研究了其自聚集行为,结果表明制得的自聚体具有较小的临界胶束浓度(CMC为1.67×10-2mg/mL).

胞内NAD(H)水平对氧化还原代谢及其他一系列生物学过程具有重要影响,但对NAD(H)的降解代谢及稳定性尚缺少充分了解.通过研究模式材料Escherichia coli中NAD的降解方式,发现NAD降解活性主要分布在胞质外,而胞内NAD降解依赖于胞外NAD降解活性.

烟酰胺腺嘌呤二核苷酸(NAD)是生物体内重要的辅酶,与其依赖的脱氢酶结合并行使催化功能时,通常以烟酰胺单核苷酸(NMN)朝向酶活性口袋内,腺嘌呤核苷酸(AMP)朝外的伸展状态形成复合物,反应过程经历结合、氢传递和解离过程.NAD与脱氢酶的结合力包括氢键、范德华力、疏水作用等,是其在生物体内参与众多生物化学反应的作用基础.

糖基化是最普遍却也最为复杂的一种蛋白质翻译后修饰.聚糖在信号传导、生物识别、胚胎发育等一系列生物过程中发挥着至关重要的功能.糖基化修饰必须得到严格的调控,其改变或失调往往伴随着各种人类疾病,如糖尿病、炎症和癌症等.
